_header(GetString, return a string describing the GLU version or GLU extensions )
42
Specifies a symbolic constant, one of
43
_gluconst(VERSION), or _gluconst(EXTENSIONS).
45
_cmnd returns a pointer to a static string describing the
46
GLU version or the GLU extensions that are supported.
48
The version number is one of the following
51
\f2major_number.minor_number\fP
53
\f2major_number.minor_number.release_number\fP.
55
The version string is of the following form:
57
\f2version number<space>vendor-specific information\fP
59
Vendor-specific information is optional.
60
Its format and contents depend on the implementation.
62
The standard GLU contains a basic set of features and capabilities.
63
If a company or group of companies wish to support other features,
64
these may be included as extensions to the GLU.
66
_gluconst(EXTENSIONS), then _cmnd
67
returns a space-separated list of names of supported GLU extensions.
68
(Extension names never contain spaces.)
70
All strings are null-terminated.
72
_cmnd only returns information about GLU extensions. Call
73
@<\f3glGetString\fP>@dnl
74
to get a list of GL extensions.
76
_cmnd is an initialization routine. Calling it after
77
a _glcmnd(NewList) results in undefined behavior.
79
NULL is returned if _param1 is not
80
_gluconst(VERSION) or _gluconst(EXTENSIONS).
