+.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.
