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_4 are defined.

Version
11 added level parameter

◆ __ast_verbose_callid()

void __ast_verbose_callid ( const char *  file,
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_threadstorage_auto()

int ast_callid_threadstorage_auto ( ast_callid callid)

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
callidpointer to store the callid
Return values
0- callid was found
1- callid was created
-1- the function failed somehow (presumably memory problems)

◆ ast_log()

void ast_log ( int  level,
const char *  file,

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
levelType of log event
fileWill be provided by the AST_LOG_* macro
lineWill be provided by the AST_LOG_* macro
functionWill be provided by the AST_LOG_* macro
fmtThis is what is important. The format is the same as your favorite breed of printf. You know how that works, right? :-)

functionWill be provided by the AST_LOG_* macro
callidThis is the ast_callid that is associated with the log message. May be NULL.
