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.
