Its format and contents depend on the implementation. .P The standard GLU contains a basic set of features and capabilities. If a company or group of companies wish to support other features, these may be included as extensions to the GLU. If \f2name\fP is \%\f3GLU_EXTENSIONS\fP, then \%\f3gluGetString\fP returns a space-separated list of names of supported GLU extensions. (Extension names never contain spaces.) .P All strings are null-terminated. .SH NOTES \%\f3gluGetString\fP only returns information about GLU extensions. Call \f3glGetString\fP to get a list of GL extensions. .P \%\f3gluGetString\fP is an initialization routine. Calling it after a \f3glNewList\fP results in undefined behavior. .SH ERRORS NULL is returned if \f2name\fP is not \%\f3GLU_VERSION\fP or \%\f3GLU_EXTENSIONS\fP. .P .SH SEE ALSO \f3glGetString\fP
