C SPECIFICATION

DESCRIPTION

       gluErrorString produces an error string from a GL  or  GLU
       error code. The string is in ISO Latin 1 format. For exam-
       ple, gluErrorString(GL_OUT_OF_MEMORY) returns  the  string
       out of memory.

       The   standard   GLU  error  codes  are  GLU_INVALID_ENUM,
       GLU_INVALID_VALUE, and GLU_OUT_OF_MEMORY.   Certain  other
       GLU  functions  can return specialized error codes through
       callbacks.  See the glGetError reference page for the list
       of GL error codes.


ERRORS

       NULL  is  returned if error is not a valid GL or GLU error
       code.
