Function Documentation

__ast_verbose()

void __ast_verbose	(	const char *	file,
		int	line,
		const char *	func,
		int	level,
		const char *	fmt,
			...
	)

Send a verbose message (based on verbose level)

This works like ast_log, but prints verbose messages to the console depending on verbosity level set.

ast_verbose(VERBOSE_PREFIX_3 "Whatever %s is happening\n", "nothing");

This will print the message to the console if the verbose level is set to a level >= 3

Note the absence of a comma after the VERBOSE_PREFIX_3. This is important. VERBOSE_PREFIX_1 through VERBOSE_PREFIX_10 are defined.

Version

11 added level parameter

		int	line,
		const char *	func,
		int	level,
		ast_callid	callid,
		const char *	fmt,
			...
	)

Send a verbose message (based on verbose level) with deliberately specified callid.

just like __ast_verbose, only __ast_verbose_callid allows you to specify which callid is being used for the log without needing to bind it to a thread. NULL is a valid argument for this function and will allow you to specify that a log will never display a call id even when there is a call id bound to the thread.

ast_callid_strnprint()

void ast_callid_strnprint	(	char *	buffer,
		size_t	buffer_size,
		ast_callid	callid
	)

copy a string representation of the callid into a target string

Parameters

buffer	destination of callid string (should be able to store 13 characters or more)
buffer_size	maximum writable length of the string (Less than 13 will result in truncation)
callid	Callid for which string is being requested

Checks thread storage for a callid and stores a reference if it exists. If not, then a new one will be created, bound to the thread, and a reference to it will be stored.

Parameters

callid

pointer to store the callid

Return values

0	- callid was found
1	- callid was created
-1	- the function failed somehow (presumably memory problems)

Parameters

callid	The callid set by ast_callid_threadstorage_auto
callid_created	The integer returned through ast_callid_threadstorage_auto

ast_log()

static void ast_log	(	int	level,
		const char *	file,
		int	line,

Used for sending a log message This is the standard logger function. Probably the only way you will invoke it would be something like this: ast_log(AST_LOG_WHATEVER, "Problem with the %s Captain. We should get some more. Will %d be enough?\n", "flux capacitor", 10); where WHATEVER is one of ERROR, DEBUG, EVENT, NOTICE, or WARNING depending on which log you wish to output to. These are implemented as macros, that will provide the function with the needed arguments.

Parameters

level	Type of log event
file	Will be provided by the AST_LOG_* macro
line	Will be provided by the AST_LOG_* macro
function	Will be provided by the AST_LOG_* macro
fmt	This is what is important. The format is the same as your favorite breed of printf. You know how that works, right? :-)
