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 typi-cally typically
       cally 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.
