- .SH NAME
- glutReportErrors - for debugging purposes; prints out OpenGL run-time errors.
- .SH SYNTAX
- .nf
- .LP
- void glutReportErrors(void);
- .SH 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
- .I glGetError
- until no more errors are reported. Any errors detected are reported
- with a GLUT warning and the corresponding text message generated by
- .I gluErrorString.
-
- Calling glutReportErrors repeatedly in your program can help isolate
- OpenGL errors to the offending OpenGL command. Remember that you
- can use the
- .I -gldebug
- option to detect OpenGL errors in any GLUT program.
- .SH SEE ALSO
- glutInit, glutCreateWindow, glutInitDisplayMode, gluErrorString, glGetError
