<B>cgSetErrorCallback</B> 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 <A HREF="cgGetError.html">cgGetError</A> to obtain the current error. To
disable the callback function, <B>cgSetErrorCallback</B>
may be called with <B>NULL</B>.

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

<PRE> void MyErrorCallback( void ) {
int myError = cgGetError();
fprintf(stderr, "CG ERROR : %s\n", cgGetErrorString(myError));
}
void main(int argc, char *argv[])

cgSetErrorCallback(MyErrorCallback);
/* Do stuff */
