const GLubyte * gluGetString( GLenum name )
Specifies a symbolic constant, one of GLU_VERSION, or GLU_EXTENSIONS.
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:
The version string is of the following form:
version number<space>vendor-specific information
Vendor-specific information is optional. Its 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.
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.
NULL is returned if name is not GLU_VERSION or GLU_EXTENSIONS.
