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.
