gluGetString.3G - Man Page

const GLubyte * gluGetString( GLenum name )

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:

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  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.
