.SH DESCRIPTION
\f3gluErrorString\fP produces an error string from a GL or GLU error code. The string
is in ISO Latin 1 format. 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.
