Function Documentation

pjmedia_audiodev_strerror()

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.

pjmedia_videodev_strerror()

pj_str_t pjmedia_videodev_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 Videodev 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.
