\f2name\fP
|
||
|
|
Specifies a symbolic constant, one of
|
||
|
|
\%\f3GLU_VERSION\fP, or \%\f3GLU_EXTENSIONS\fP.
|
||
|
|
.SH DESCRIPTION
|
||
|
|
\%\f3gluGetString\fP returns a pointer to a static string describing the
|
||
|
|
GLU version or the GLU extensions that are supported.
|
||
|
|
.P
|
||
|
|
The version number is one of the following
|
||
|
|
forms:
|
||
|
|
.P
|
||
|
|
\f2major_number.minor_number\fP
|
||
|
|
.br
|
||
|
|
\f2major_number.minor_number.release_number\fP.
|
||
|
|
.P
|
||
|
|
The version string is of the following form:
|
||
|
|
.P
|
||
|
|
\f2version number<space>vendor-specific information\fP
|
||
|
|
.P
|
||
|
|
Vendor-specific information is optional.
|
||
|
|
Its and contents depend on the implementation.
|
||
|
|
.P
|
||
|
|
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 \f2name\fP is
|
||
|
|
\%\f3GLU_EXTENSIONS\fP, then \%\f3gluGetString\fP
|
||
|
|
returns a space-separated list of names of supported GLU extensions.
|
||
|
|
(Extension names never contain spaces.)
|
||
|
|
.P
|
||
|
|
All strings are null-terminated.
|
||
|
|
.SH NOTES
|
||
|
|
\%\f3gluGetString\fP only returns information about GLU extensions. Call
|
||
|
|
\f3glGetString\fP to get a list of GL extensions.
|
||
|
|
.P
|
||
|
|
\%\f3gluGetString\fP is an initialization routine. Calling it after
|
||
|
|
a \f3glNewList\fP results in undefined behavior.
|
||
|
|
.SH ERRORS
|
||
|
|
NULL is returned if \f2name\fP is not
|
||
|
|
\%\f3GLU_VERSION\fP or \%\f3GLU_EXTENSIONS\fP.
