gluErrorString — produce an error string from a GL or GLU error code

C Specification

const GLubyte * gluErrorString(GLenum error);



Specifies a GL or GLU error code.


gluErrorString produces an error string from a GL or GLU error code. The string is in ISO Latin 1 format. For example, gluErrorString(GLU_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.


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