Returns a string describing the GLU version or GLU extensions.
const GLubyte * gluGetString( GLenum name)
The gluGetString subroutine 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.
| name | Specifies a symbolic constant, one of GLU_VERSION, or GLU_EXTENSIONS. |
The gluGetString subroutine only returns information about GLU extensions. Call glGetString to get a list of GL extensions.
The gluGetString subroutine 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.
