Name of OpenGL extension.

Description
glutExtensionSupported
helps to easily determine whether a given OpenGL extension is supported or
not. The extension parameter names the extension to query. The supported extensions can also be determined with
glGetString(GL_EXTENSIONS)
, but
glutExtensionSupported
does the correct parsing of the returned string.
glutExtensionSupported
returns non-zero if the extension is supported, zero if not supported.
There must be a valid current window to call
glutExtensionSupported
.
glutExtensionSupported
only returns information about OpenGL extensions only. This means window
system dependent extensions (for example, GLX extensions) are not reported by
glutExtensionSupported
.
Example
Here is an example of using glutExtensionSupported:
if (!glutExtensionSupported("GL_EXT_texture")) {
fprintf(stderr, "Missing the texture extension!);
exit(1);
}
Notice that the name argument includes both the GL prefix and the extension family prefix (EXT).
