glutReportErrors(3GLUT) GLUT glutReportErrors(3GLUT)
NAME
glutReportErrors - for debugging purposes; prints out OpenGL run-time
errors.
SYNTAX
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 gluErrorString.
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.
