Functions
-
pj_str_t
pjmedia_audiodev_strerror
(pj_status_t status, char *buffer, pj_size_t bufsize)¶ Get error message for the specified error code. Note that this function is only able to decode PJMEDIA Audiodev specific error code. Application should use pj_strerror(), which should be able to decode all error codes belonging to all subsystems (e.g. pjlib, pjmedia, pjsip, etc).
- Parameters
status – The error code.
buffer – The buffer where to put the error message.
bufsize – Size of the buffer.
- Returns
The error message as NULL terminated string, wrapped with pj_str_t.
