.SH DESCRIPTION
\%\f3gluErrorString\fP produces an error string from a GL or GLU error code. The string
is in ISO Latin 1 . For example,
\%\f3gluErrorString\fP(\%\f3GL_OUT_OF_MEMORY\fP) returns the string
\f2out of memory\fP.
.P
The standard GLU error codes are \%\f3GLU_INVALID_ENUM\fP,
\%\f3GLU_INVALID_VALUE\fP,
and \%\f3GLU_OUT_OF_MEMORY\fP.
Certain other GLU functions can return specialized error codes
through callbacks.
See the \f3glGetError\fP reference page for the list of
GL error codes.
.SH ERRORS
\%\f3NULL\fP is returned if \f2error\fP is not a valid GL or GLU error code.
