9.5 glutExtensionSupportedglutExtensionSupported helps to easily determine whether a given OpenGL extension is supported. Usage int glutExtensionSupported(char *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.
