NAME    [Toc]    [Back]

     vlPerror, vlStrError, vlGetErrno, vlErrno - VL error routines

SYNOPSIS    [Toc]    [Back]

     #include <dmedia/vl.h>

     void vlPerror(const char *str);
     char *vlStrError(int errnum);
     int vlGetErrno(void);
     int vlErrno;

PARAMETERS    [Toc]    [Back]

     str      String to	be prefixed before error message.

     errnum   VL error number.

DESCRIPTION    [Toc]    [Back]

     vlPerror takes a pointer to a character array containing message to be
     printed along with	the message associated with the	error number in
     vlPerror and prints both on stderr.

     vlStrError	takes a	value representing the error number and	returns	the
     string representing the VL	error number specified.

     vlGetErrno	returns	the per-process	VL error number	for the	calling
     thread. The internal setting and public retrieval of the VL error value
     is	guaranteed to be thread-safe.

     vlErrno is	a global variable set in the library when an error has
     occured. This should not be directly accessed, instead use	the vlGetErrno
     call. This	variable is maintained for compatibility only. Unlike the
     values returned by	vlGetErrno, vlErrno is not a per-thread	value.

RETURN VALUE    [Toc]    [Back]

     vlStrError	returns	a pointer to a character array representing the
     description of the	VL error number	specified.
