null-terminated and contains a space-separated list of extension names. (The extension names themselves never contain spaces.) If there are
no extensions to GLX, then the empty string is returned.
NOTES
glXQueryExtensionsString is available only if the GLX version is 1.1 or greater.
glXQueryExtensionsString only returns information about GLX extensions. Call glGetString() to get a list of GL extensions.

glXGetClientString - return a string describing the client
C SPECIFICATION
const char * glXGetClientString(Display * dpy, int name);
PARAMETERS
dpy
Specifies the connection to the X server.
name
Specifies which string is returned. The symbolic constants GLX_VENDOR, GLX_VERSION, and GLX_EXTENSIONS are accepted.
DESCRIPTION
glXGetClientString 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.
NOTES
glXGetClientString 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 glGetString() to get a list of GL extensions
supported by the server.
