glutReportErrors(3GLUT) GLUT glutReportErrors(3GLUT)
NAME
glutReportErrors - for debugging purposes; prints out OpenGL run-time errors.
SYNTAX
#include <GLUT/glut.h>
void glutReportErrors(void);
DESCRIPTION
This routine prints out any OpenGL run-time errors pending and clears the errors. This routine typically should only be used for debugging
purposes since calling it will slow OpenGL programs. It is provided as a convenience; all the routine does is call glGetError until no
more errors are reported. Any errors detected are reported with a GLUT warning and the corresponding text message generated by gluEr-
rorString.
Calling glutReportErrors repeatedly in your program can help isolate OpenGL errors to the offending OpenGL command. Remember that you can
use the -gldebug option to detect OpenGL errors in any GLUT program.
