C SPECIFICATION

int name )
PARAMETERS
dpy Specifies the connection to the X server.
name Specifies which string is returned. One of GLX_VENDOR,
GLX_VERSION, or GLX_EXTENSIONS.
DESCRIPTIONglXGetClientString returns a string describing some aspect of the client
library. The possible values for name are GLX_VENDOR, GLX_VERSION, and
GLX_EXTENSIONS. If name is not set to one of these values,
glXGetClientString returns NULL. The format and contents of the vendor
string is implementation dependent.
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.
The version string is laid out as follows:
<major_version.minor_version><space><vendor-specific info>
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.
NOTESglXGetClientString 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.
glXGetClientString only returns information about GLX extensions
supported by the client. Call glXGetString to get a list of GL extensions
supported by the server.
