GLUGETSTRING(3G)GLUGETSTRING(3G)NAME
gluGetString - return a string describing the GLU version or GLU extensions
C SPECIFICATION
const GLubyte * gluGetString( GLenum name )
PARAMETERS
name Specifies a symbolic constant, one of GLU_VERSION, or GLU_EXTENSIONS.
DESCRIPTION
gluGetString 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:
major_number.minor_number
major_number.minor_number.release_number.
The version string is of the following form:
version number<space>vendor-specific information
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 name is GLU_EXTENSIONS, then gluGetString returns a space-separated list of names of
supported GLU extensions. (Extension names never contain spaces.)
All strings are null-terminated.
NOTES
gluGetString only returns information about GLU extensions. Call glGetString to get a list of GL extensions.
gluGetString is an initialization routine. Calling it after a glNewList results in undefined behavior.
ERRORS
NULL is returned if name is not GLU_VERSION or GLU_EXTENSIONS.

gluCheckExtension - determines if an extension name is supported
C SPECIFICATION
GLboolean gluCheckExtension(const GLubyte * extName, const GLubyte * extString);
PARAMETERS
extName
Specifies an extension name.
extString
Specifies a space-separated list of extension names supported.
DESCRIPTION
gluCheckExtension returns GLU_TRUE if extName is supported otherwise GLU_FALSE is returned.
This is used to check for the presence for OpenGL, GLU, or GLX extension names by passing the extension strings returned by glGetString(),
gluGetString(), glXGetClientString(), glXQueryExtensionsString(), or glXQueryServerString(), respectively, as extString.
NOTES
Cases where one extension name is a substring of another are correctly handled.
There may or may not be leading or trailing blanks in extString.
Extension names should not contain embedded spaces.
All strings are null-terminated.
