glutreporterrors(3)
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 com
mand. Remember that you can use the -gldebug option to
detect OpenGL errors in any GLUT program.
