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.
