<HTML><BODY><PRE>     <STRONG>NAME</STRONG>	  <STRONG>fgluGetString</STRONG>	- return a string describing the GLU version	  or GLU extensions     <STRONG>FORTRAN</STRONG> <STRONG>SPECIFICATION</STRONG>	  CHARACTER*256	 <STRONG>fgluGetString</STRONG>(	INTEGER*4 <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>fgluGetString</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>&lt;<EM>space</EM>&gt;<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>fgluGetString</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>fgluGetString</STRONG>	only returns information about GLU extensions.	  Call <STRONG>glGetString</STRONG> to get a list of GL extensions.	  <STRONG>fgluGetString</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>.     <STRONG>SEE</STRONG> <STRONG>ALSO</STRONG>	  <STRONG>glGetString</STRONG></PRE></BODY></HTML>
