C SPECIFICATION

void gluQuadricCallback(GLUquadric* quad, GLenum which, _GLUfuncptr CallBackFunc);

DESCRIPTION

gluQuadricCallback is used to define a new callback to be used by a quadrics object. If the specified callback is already defined, then it is replaced. If CallBackFunc is NULL, then any existing callback is erased.

GLU_ERROR

The function is called when an error is encountered. Its single argument is of type GLenum, and it indicates the specific error that occurred. Character strings describing these errors can be retrieved with the gluErrorString() call.
