<STRONG>NAME</STRONG>
<STRONG>gluGetString</STRONG> - return a string describing the GLU version or
GLU extensions
<STRONG>C</STRONG> <STRONG>SPECIFICATION</STRONG>
const GLubyte * <STRONG>gluGetString</STRONG>( GLenum <EM>name</EM> )
<STRONG>PARAMETERS</STRONG>
<EM>name</EM> Specifies a symbolic constant, one of <STRONG>GLU_VERSION</STRONG>, or
<STRONG>GLU_EXTENSIONS</STRONG>.
<STRONG>DESCRIPTION</STRONG>
<STRONG>gluGetString</STRONG> returns a pointer to a static string describing
the GLU version or the GLU extensions that are supported.
The version number is one of the following forms:
<EM>major</EM>_<EM>number</EM>.<EM>minor</EM>_<EM>number</EM>
<EM>major</EM>_<EM>number</EM>.<EM>minor</EM>_<EM>number</EM>.<EM>release</EM>_<EM>number</EM>.
The version string is of the following form:
<EM>version</EM> <EM>number</EM><<EM>space</EM>><EM>vendor</EM>-<EM>specific</EM> <EM>information</EM>
Vendor-specific information is optional. Its format and
contents depend on the implementation.
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 <EM>name</EM> is <STRONG>GLU_EXTENSIONS</STRONG>, then <STRONG>gluGetString</STRONG>
returns a space-separated list of names of supported GLU
extensions. (Extension names never contain spaces.)
All strings are null-terminated.
<STRONG>NOTES</STRONG>
<STRONG>gluGetString</STRONG> only returns information about GLU extensions.
Call <STRONG>glGetString</STRONG> to get a list of GL extensions.
<STRONG>gluGetString</STRONG> is an initialization routine. Calling it after
a <STRONG>glNewList</STRONG> results in undefined behavior.
<STRONG>ERRORS</STRONG>
NULL is returned if <EM>name</EM> is not <STRONG>GLU_VERSION</STRONG> or
<STRONG>GLU_EXTENSIONS</STRONG>.
