Starts reading from a file.

Parameters:
filename the name of the file to read from
type format of file you wish to read from
comment comment to go with
flags file flags
check (unimplemented, hence negligible)
mode Open mode Open an incoming file stream. flags are flags for the open() command, and if check is non-zero, then it will not read a file if there are any files that start with that name and have an extension Please note, this is a blocking function. Program execution will not return until ast_waitstream completes it's execution.
Return values:
a struct ast_filestream on success.

int ast_writestream ( struct ast_filestream fs,
struct ast_frame f 
)

Writes a frame to a stream.

Parameters:
fs filestream to write to
f frame to write to the filestream Send a frame to a filestream -- note: does NOT free the frame, call ast_frfree manually
Return values:
0 on success.
-1 on failure.
