#define AST_APP_OPTION ( option,
flagno   )     [option] = { .flag = flagno }

Declares an application option that does not accept an argument.

Parameters:
option The single character representing the option
flagno The flag index to be set if this option is present
See also:
AST_APP_OPTIONS, ast_app_parse_options

Definition at line 469 of file app.h.

#define AST_APP_OPTION_ARG ( option,
flagno,
argno   )     [option] = { .flag = flagno, .arg_index = argno + 1 }

Declares an application option that accepts an argument.

Parameters:
option The single character representing the option
flagno The flag index to be set if this option is present
argno The index into the argument array where the argument should be placed

Definition at line 480 of file app.h.

#define AST_APP_OPTIONS ( holder,
options...   )     static const struct ast_app_option holder[128] = options

Declares an array of options for an application.

Parameters:
holder The name of the array to be created
options The actual options to be placed into the array
See also:
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 {
        OPT_JUMP = (1 << 0),
        OPT_BLAH = (1 << 1),
        OPT_BLORT = (1 << 2),
  } my_app_option_flags;

  enum {
        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,
  } my_app_option_args;

  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_parseoptions(my_app_options, &opts, opt_args, options)) {
      ast_module_user_remove(u);
      return -1;
   }
  }

#define AST_DECLARE_APP_ARGS ( name,
arglist   )     AST_DEFINE_APP_ARGS_TYPE(, arglist) name

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.

#define AST_DEFINE_APP_ARGS_TYPE ( type,

Value:

struct type { \
      unsigned int argc; \
      char *argv[0]; \
      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.

int 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 The channel to read from
prompt The file to stream to the channel
s The string to read in to. Must be at least the size of your length
maxlen How many digits to read (maximum)
timeout set timeout to 0 for "standard" timeouts. Set timeout to -1 for "ludicrous time" (essentially never times out)

unsigned int ast_app_separate_args ( char *  buf,
char  delim,
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
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.

int ast_dtmf_stream ( struct ast_channel chan,
struct ast_channel peer,
const char *  digits,
int  between,
unsigned int  duration 
)

Send DTMF to a channel.

Parameters:
chan The channel that will receive the DTMF frames
peer (optional) Peer channel that will be autoserviced while the primary channel is receiving DTMF
digits This is a string of characters representing the DTMF 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' to add a 500 millisecond pause to the DTMF sequence.
between This is the number of milliseconds to wait in between each DTMF digit. If zero milliseconds is specified, then the default value of 100 will be used.
duration This is the duration that each DTMF digit should have.

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*().
