<para>

<function>glXGetClientString</function> returns a string
|
||
|
|
describing some aspect of the client library. The possible values for <parameter>name</parameter>
|
||
|
|
are <constant>GLX_VENDOR</constant>, <constant>GLX_VERSION</constant>, and
|
||
|
|
<constant>GLX_EXTENSIONS</constant>. If <parameter>name</parameter>
|
||
|
|
is not set to one of these values, <function>glXGetClientString</function> returns <constant>NULL</constant>.
|
||
|
|
The format and contents of the vendor string is implementation dependent.
|
||
|
|
</para>
|
||
|
|
<para>
|
||
|
|
The extensions string is null-terminated and contains a
|
||
|
|
space-separated list of extension names. (The extension names never
|
||
|
|
contain spaces.)
|
||
|
|
If there are no extensions to GLX, then the empty string is returned.
|
||
|
|
</para>
|
||
|
|
<para>
|
||
|
|
The version string is laid out as follows:
|
||
|
|
</para>
|
||
|
|
<para>
|
||
|
|
<major_version.minor_version><space><vendor-specific info>
|
||
|
|
</para>
|
||
|
|
<para>
|
||
|
|
Both the major and minor portions of the version number are of arbitrary
|
||
|
|
length. The vendor-specific information is optional. However, if it is
|
||
|
|
present, the format and contents are implementation specific.

<para>

<function>glXGetClientString</function> is available only if the GLX version is 1.1 or greater.

If the GLX version is 1.1 or 1.0, the GL version must be 1.0.
|

|
|
If the GLX version is 1.2, then the GL version must be 1.1.
|
||
|
|
If the GLX version is 1.3, then the GL version must be 1.2.
|

<para>
|

<function>glXGetClientString</function> only returns information about GLX extensions supported by the client.

Call <citerefentry><refentrytitle>glGetString</refentrytitle></citerefentry> to get a list of GL extensions supported by the server.
