Macro Definition Documentation

◆ ast_cli_command

#define ast_cli_command (   fd,
 
)    ast_cli_command_full(CLI_NO_PERMS, CLI_NO_PERMS, fd, s)

Definition at line 232 of file cli.h.

◆ ast_cli_command_multiple

#define ast_cli_command_multiple (   fd,
  size,
 
)    ast_cli_command_multiple_full(CLI_NO_PERMS, CLI_NO_PERMS, fd, size, s)

Definition at line 248 of file cli.h.

◆ AST_CLI_COMPLETE_EOF

#define AST_CLI_COMPLETE_EOF   "_EOF_"

Definition at line 52 of file cli.h.

◆ AST_CLI_DEFINE

#define AST_CLI_DEFINE (   fn,
  txt,
  ... 
)    { .handler = fn, .summary = txt, ## __VA_ARGS__ }
Examples
app_skel.c.

Definition at line 197 of file cli.h.

◆ AST_CLI_ONOFF

#define AST_CLI_ONOFF (   x)    (x) ? "On" : "Off"

return On or Off depending on the argument. This is used in many places in CLI command, having a function to generate this helps maintaining a consistent output (and possibly emitting the output in other languages, at some point).

Definition at line 78 of file cli.h.

◆ ast_cli_register

#define ast_cli_register (   e)    __ast_cli_register(e, AST_MODULE_SELF)

Registers a command or an array of commands.

Parameters
ewhich cli entry to register. Register your own command
Return values
0on success
-1on failure

Definition at line 256 of file cli.h.

◆ ast_cli_register_multiple

#define ast_cli_register_multiple (   e,
  len 
)     __ast_cli_register_multiple(e, len, AST_MODULE_SELF)

Register multiple commands.

Parameters
epointer to first cli entry to register
lennumber of entries to register
Examples
app_skel.c.

Definition at line 265 of file cli.h.

◆ AST_CLI_YESNO

#define AST_CLI_YESNO (   x)    AST_YESNO(x)

Return Yes or No depending on the argument.

Note that this should probably still be used for CLI commands instead of AST_YESNO(), in the off chance we someday want to translate the CLI.

Parameters
xBoolean value
Returns
"Yes" if x is true (non-zero)
"No" if x is false (zero)
Examples
app_skel.c.

Definition at line 71 of file cli.h.

◆ AST_MAX_ARGS

#define AST_MAX_ARGS   64

Definition at line 50 of file cli.h.

◆ AST_MAX_CMD_LEN

#define AST_MAX_CMD_LEN   16

Definition at line 48 of file cli.h.

◆ CLI_FAILURE

#define CLI_FAILURE   (char *)RESULT_FAILURE

Definition at line 46 of file cli.h.

◆ CLI_NO_PERMS

#define CLI_NO_PERMS   -1

Definition at line 38 of file cli.h.

◆ CLI_SHOWUSAGE

#define CLI_SHOWUSAGE   (char *)RESULT_SHOWUSAGE

Definition at line 45 of file cli.h.

◆ CLI_SUCCESS

#define CLI_SUCCESS   (char *)RESULT_SUCCESS
Examples
app_skel.c.

Definition at line 44 of file cli.h.

◆ ESS

#define ESS (   x)    ((x) == 1 ? "" : "s")

In many cases we need to print singular or plural words depending on a count. This macro helps us e.g. printf("we have %d object%s", n, ESS(n));

Definition at line 59 of file cli.h.

◆ RESULT_FAILURE

#define RESULT_FAILURE   2

Definition at line 42 of file cli.h.

◆ RESULT_SHOWUSAGE

#define RESULT_SHOWUSAGE   1

Definition at line 41 of file cli.h.

◆ RESULT_SUCCESS

#define RESULT_SUCCESS   0

Definition at line 40 of file cli.h.

◆ ast_cli_allow_at_shutdown()

int ast_cli_allow_at_shutdown ( struct ast_cli_entry e)

Allow a CLI command to be executed while Asterisk is shutting down.

CLI commands by defeault are disabled when Asterisk is shutting down. This is to ensure the safety of the shutdown since CLI commands may attempt to access resources that have been freed as a result of the shutdown.

If a CLI command should be allowed at shutdown, then the best way to enable this is to call ast_cli_allow_at_shutdown during the CLI_INIT state of the CLI handler.

◆ ast_cli_completion_add()

int ast_cli_completion_add ( char *  value)

Add a result to a request for completion options.

Parameters
valueA completion option text.
Return values
0Success
-1Failure

This is an alternative to returning individual values from CLI_GENERATE. Instead of repeatedly being asked for the next match and having to start over, you can call this function repeatedly from your own stateful loop. When all matches have been added you can return NULL from the CLI_GENERATE function.

Note
This function always eventually results in calling ast_free on value.

◆ ast_cli_completion_matches()

char** ast_cli_completion_matches ( const char *  text,
const char *  word 
)

Generates a NULL-terminated array of strings that 1) begin with the string in the second parameter, and 2) are valid in a command after the string in the first parameter.

The first entry (offset 0) of the result is the longest common substring in the results, useful to extend the string that has been completed. Subsequent entries are all possible values, followed by a NULL. All strings and the array itself are malloc'ed and must be freed by the caller.

Warning
This function cannot be called recursively so it will always fail if called from a CLI_GENERATE callback.

◆ ast_cli_completion_vector()

struct ast_vector_string* ast_cli_completion_vector ( const char *  text,

Generates a vector of strings for CLI completion.

Parameters
textComplete input being matched.
wordCurrent word being matched

The results contain strings that both: 1) Begin with the string in word. 2) Are valid in a command after the string in text.

The first entry (offset 0) of the result is the longest common substring in the results, useful to extend the string that has been completed. Subsequent entries are all possible values.

Note
All strings and the vector itself are malloc'ed and must be freed by the caller.
The vector is sorted and does not contain any duplicates.

char* ast_complete_channels ( const char *  line,
const char *  word,
int  pos,
int  state,
int  rpos 
)

Command completion for the list of active channels.

This can be called from a CLI command completion function that wants to complete from the list of active channels. 'rpos' is the required position in the command. This function will return NULL immediately if 'rpos' is not the same as the current position, 'pos'.
