glXQueryServerString Subroutine

OpenGL 1.2 for AIX: Reference Manual

glXQueryServerString Subroutine

Purpose

Returns string describing the server

Library

C bindings library: libGL.a

C Syntax

const char *glXQueryServerString(Display   *dpy,
    int   screen,
    int   name)

Description

The glXQueryServerString subroutine returns a pointer to a static, null-terminated string describing some aspect of the server's GLX extension. The possible values for name and the format of the strings is the same as for glXGetClientString. If name is not set to a recognized value, NULL is returned.

Parameters

dpy	Specifies the connection to the X server.
screen	Specifies the screen number.
name	Specifies which string is returned. One of GLX_VENDOR, GLX_VERSION, or GLX_EXTENSIONS.

Notes

The glXQueryServerString subroutine 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, the GL version must be 1.1.

The glXQueryServerString subroutine only returns information about GLX extensions supported by the server. Call glGetString to get a list of GL extensions. Call glXGetClientString to get a list of GLX extensions supported by the client.
