ast_app_parse_options

This macro declares a 'static const' array of struct ast_option elements to hold the list of available options for an application. Each option must be declared using either the AST_APP_OPTION() or AST_APP_OPTION_ARG() macros.

Example usage:

enum my_app_option_flags {
      OPT_JUMP = (1 << 0),
      OPT_BLAH = (1 << 1),
      OPT_BLORT = (1 << 2),
};
 
enum my_app_option_args {
      OPT_ARG_BLAH = 0,
      OPT_ARG_BLORT,
      !! this entry tells how many possible arguments there are,
         and must be the last entry in the list
      OPT_ARG_ARRAY_SIZE,
};
 
AST_APP_OPTIONS(my_app_options, {
      AST_APP_OPTION('j', OPT_JUMP),
      AST_APP_OPTION_ARG('b', OPT_BLAH, OPT_ARG_BLAH),
      AST_APP_OPTION_BLORT('B', OPT_BLORT, OPT_ARG_BLORT),
});
 
static int my_app_exec(struct ast_channel *chan, void *data)
{
    char *options;
  struct ast_flags opts = { 0, };
  char *opt_args[OPT_ARG_ARRAY_SIZE];
 
    ... do any argument parsing here ...
 
  if (ast_app_parse_options(my_app_options, &opts, opt_args, options)) {
    return -1;
  }
}

ast_app_separate_args

#define ast_app_separate_args	(		a,
			b,
			c,
			d
	)		__ast_app_separate_args(a,b,1,c,d)

Definition at line 1319 of file include/asterisk/app.h.

AST_DECLARE_APP_ARGS

#define AST_DECLARE_APP_ARGS	(		name,
			arglist
	)		AST_DEFINE_APP_ARGS_TYPE(argtype_##name, arglist) name = { 0, }

Declare a structure to hold an application's arguments.

Parameters

name	The name of the structure
arglist	The list of arguments, defined using AST_APP_ARG

This macro declares a structure intended to be used in a call to ast_app_separate_args(). The structure includes all the arguments specified, plus an argv array that overlays them and an argc argument counter. The arguments must be declared using AST_APP_ARG, and they will all be character pointers (strings).

Note

The structure is not initialized, as the call to ast_app_separate_args() will perform that function before parsing the arguments.

Examples

app_skel.c.

Definition at line 1247 of file include/asterisk/app.h.

AST_DEFINE_APP_ARGS_TYPE

#define AST_DEFINE_APP_ARGS_TYPE	(		type,
			arglist
	)

Define a structure type to hold an application's arguments.

Parameters

type	The name of the structure type
arglist	The list of arguments, defined using AST_APP_ARG

This macro defines a structure type intended to be used in a call to ast_app_separate_args(). The structure includes all the arguments specified, plus an argv array that overlays them and an argc argument counter. The arguments must be declared using AST_APP_ARG, and they will all be character pointers (strings).

Note

This defines a structure type, but does not declare an instance of the structure. That must be done separately.

Definition at line 1264 of file include/asterisk/app.h.

AST_IVR_DECLARE_MENU

#define AST_IVR_DECLARE_MENU	(		holder,
			title,
			flags,
			foo...
	)

Value:

    static struct ast_ivr_option __options_##holder[] = foo;\
    static struct ast_ivr_menu holder = { title, flags, __options_##holder }

Definition at line 108 of file include/asterisk/app.h.

AST_IVR_FLAG_AUTORESTART

#define AST_IVR_FLAG_AUTORESTART   (1 << 0)

Definition at line 106 of file include/asterisk/app.h.

AST_NONSTANDARD_APP_ARGS

#define AST_NONSTANDARD_APP_ARGS	(		args,
			parse,
			sep
	)		args.argc = __ast_app_separate_args(parse, sep, 1, args.argv, ((sizeof(args) - offsetof(typeof(args), argv)) / sizeof(args.argv[0])))

Performs the 'nonstandard' argument separation process for an application.

Parameters

args	An argument structure defined using AST_DECLARE_APP_ARGS
parse	A modifiable buffer containing the input to be parsed

__ast_app_separate_args()

unsigned int __ast_app_separate_args	(	char *	buf,
		char	delim,
		int	remove_chars,
		char **	array,
		int	arraylen
	)

Separate a string into arguments in an array.

Parameters

buf	The string to be parsed (this must be a writable copy, as it will be modified)
delim	The character to be used to delimit arguments
remove_chars	Remove backslashes and quote characters, while parsing
array	An array of 'char *' to be filled in with pointers to the found arguments
arraylen	The number of elements in the array (i.e. the number of arguments you will accept)

Note: if there are more arguments in the string than the array will hold, the last element of the array will contain the remaining arguments, not separated.

The array will be completely zeroed by this function before it populates any entries.

Returns

The number of arguments found, or zero if the function arguments are not valid.

ast_app_exec_sub()

int ast_app_exec_sub	(	struct ast_channel *	autoservice_chan,
		struct ast_channel *	sub_chan,
		const char *	sub_args,
		int	ignore_hangup
	)

Run a subroutine on a channel, placing an optional second channel into autoservice.

Since

11

This is a shorthand method that makes it very easy to run a subroutine on any given channel. It is perfectly reasonable to supply a NULL autoservice_chan here in case there is no channel to place into autoservice.

Note

Absolutely NO channel locks should be held before calling this function.

Parameters

autoservice_chan	A channel to place into autoservice while the subroutine is run
sub_chan	Channel to execute subroutine on.
sub_args	Gosub application argument string.
ignore_hangup	TRUE if a hangup does not stop execution of the routine.

Return values

0	success
-1	on error

ast_app_getdata()

enum ast_getdata_result ast_app_getdata	(	struct ast_channel *	c,
		const char *	prompt,
		char *	s,
		int	maxlen,
		int	timeout
	)

Plays a stream and gets DTMF data from a channel.

Parameters

c	Which channel one is interacting with
prompt	File to pass to ast_streamfile (the one that you wish to play). It is also valid for this to be multiple files concatenated by "&". For example, "file1&file2&file3".
s	The location where the DTMF data will be stored
maxlen	Max Length of the data
timeout	Timeout length waiting for data(in milliseconds). Set to 0 for standard timeout(six seconds), or -1 for no time out.

This function was designed for application programmers for situations where they need to play a message and then get some DTMF data in response to the message. If a digit is pressed during playback, it will immediately break out of the message and continue execution of your code.

		struct ast_channel *	sub_chan,
		const char *	sub_location,
		const char *	sub_args,
		int	ignore_hangup
	)

Run a subroutine on a channel, placing an optional second channel into autoservice.

Since

11

This is a shorthand method that makes it very easy to run a subroutine on any given channel. It is perfectly reasonable to supply a NULL autoservice_chan here in case there is no channel to place into autoservice.

Note

Absolutely NO channel locks should be held before calling this function.

Parameters

autoservice_chan	A channel to place into autoservice while the subroutine is run
sub_chan	Channel to execute subroutine on.
sub_location	The location of the subroutine to run.
sub_args	The arguments to pass to the subroutine.
ignore_hangup	TRUE if a hangup does not stop execution of the routine.

Return values

0	success
-1	on error

Send a string of MF digits to a channel.

Parameters

chan	The channel that will receive the MF digits.
peer	(optional) Peer channel that will be autoserviced while the primary channel is receiving MF
chan2	A second channel that will simultaneously receive MF digits. This option may only be used if is_external is 0.
digits	This is a string of characters representing the MF digits to be sent to the channel. Valid characters are "0123456789*#abcdABCD". Note: You can pass arguments 'f' or 'F', if you want to Flash the channel (if supported by the channel), or 'w' or 'W' to add a wink (if supported by the channel).
between	This is the number of milliseconds to wait in between each MF digit. If zero milliseconds is specified, then the default value of 50 will be used.
duration	This is the duration that each numeric MF digit should have. Default value is 55.
durationkp	This is the duration that each KP digit should have. Default is 120.
durationst	This is the duration that each ST, STP, ST2P, or ST3P digit should have. Default is 65.
is_external	1 if called by a thread that is not the channel's media handler thread, 0 if called by the channel's media handler thread.

Return values

0	on success.
-1	on failure or a channel hung up.

		int	maxsilence_ms
	)

Record a file based on input frm a channel. Recording is performed in 'prepend' mode which works a little differently from normal recordings This function will not play a success message due to post-recording control in the application this was added for.

Parameters

chan	the channel being recorded
playfile	Filename of sound to play before recording begins
recordfile	Filename to save the recording
maxtime_sec	Longest possible message length in seconds
fmt	string containing all formats to be recorded delimited by '|'
duration	pointer to integer for storing length of the recording
sound_duration	pointer to integer for storing length of the recording minus all silence
beep	whether to play a beep to prompt the recording
silencethreshold	tolerance of noise levels that can be considered silence for the purpose of silence timeout, -1 for default
maxsilence_ms	length of time in milliseconds which will trigger a timeout from silence, -1 for default.

Return values

-1	failure or hangup
'S'	Recording ended from silence timeout
't'	Recording either exceeded maximum duration or the call was ended via DTMF

ast_replace_sigchld()

void ast_replace_sigchld

(

void

)

Replace the SIGCHLD handler.

Normally, Asterisk has a SIGCHLD handler that is cleaning up all zombie processes from forking elsewhere in Asterisk. However, if you want to wait*() on the process to retrieve information about it's exit status, then this signal handler needs to be temporarily replaced.

Code that executes this function must call ast_unreplace_sigchld() after it is finished doing the wait*().

    unsigned int level;
 
    level = safe_system_level++;

ast_safe_execvp()

int ast_safe_execvp	(	int	dualfork,
		const char *	file,
		char *const	argv[]
	)

Safely spawn an external program while closing file descriptors.

Note

This replaces the execvp call in all Asterisk modules

Parameters

dualfork	Non-zero to simulate running the program in the background by forking twice. The option provides similar functionality to the '&' in the OS shell command "cmd &". The option allows Asterisk to run a reaper loop to watch the first fork which immediately exits after spaning the second fork. The actual program is run in the second fork.
file	execvp(file, argv) file parameter
argv	execvp(file, argv) argv parameter
