mvGetErrno(3dm)						       mvGetErrno(3dm)

NAME    [Toc]    [Back]

     mvGetErrno, mvClearErrno, mvGetErrorStr - return information for Movie
     Library error codes

SYNOPSIS    [Toc]    [Back]

     #include <dmedia/moviefile.h>

     int mvGetErrno();

     const char* mvGetErrorStr(int error);

     void mvClearErrno(void);

DESCRIPTION    [Toc]    [Back]

     mvGetErrno(3dm) returns the error code set	by the last Movie Library
     function that returned an error (DM_FAILURE).

     mvGetErrorStr(3dm)	returns	an error string	corresponding to error.

     mvClearErrno(3dm) sets the	error code stored in the Movie Library to

     If	the value of dmGetErrno(3dm) does not match one	of the error codes
     outlined in moviefile.h, it will match one	of the system error codes
     outlined in <sys/errno.h>.

     Besides error codes which are returned by Movie Library function calls,
     errors encountered	while playing a	movie are sent to the client
     application via the Movie Library event queue.  In	that case, the value
     of	the error code contained in the	event corresponds to the error codes
     listed in moviefile.h, and	may be passed to mvGetErrorStr(3dm) to receive
     a valid error string.  See	the manual page	for mvNextEvent(3dm).
