Cg Core Runtime API                         cgSetErrorCallback(3)



NAME
     cgSetErrorCallback - set the error callback function

SYNOPSIS
       #include 

       typedef void (*CGerrorCallbackFunc)( void );

       void cgSetErrorCallback( CGerrorCallbackFunc func );


PARAMETERS
     func    A function pointer to the error callback function.

RETURN VALUES
     None.

DESCRIPTION
     cgSetErrorCallback sets a callback function that will be
     called every time an error occurrs.  The callback function
     is not passed any parameters.  It is assumed that the
     callback function will call cgGetError to obtain the current
     error.  To disable the callback function, cgSetErrorCallback
     may be called with NUL.

EXAMPLES
     The following is an example of how to set and use an error
     callback :

       void MyErrorCallback( void ) {
         int myError = cgGetError();
         fprintf(stderr, "CG EROR : %s\n", cgGetErrorString(myError));
       }

       void main(int argc, char *argv[])
       {
         cgSetErrorCallback(MyErrorCallback);

         /* Do stuff */
       }


ERORS
     None.

HISTORY
     cgSetErrorCallback was introduced in Cg 1.1.
