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 <I>glGetError</I> until no more errors are reported. Any errors detected are reported with a GLUT warning and the corresponding text message generated by <I>gluErrorString.</I> Calling glutReportErrors repeatedly in your program can help isolate OpenGL errors to the offending OpenGL command. Remember that you can use the <I>-gldebug</I> option to detect OpenGL errors in any GLUT program. <A NAME="lbAE"> </A> <H2>SEE ALSO</H2> glutInit, glutCreateWindow, glutInitDisplayMode, gluErrorString, glGetError <A NAME="lbAF"> </A> <H2>AUTHOR</H2> Mark J.
