NAME
gluCheckExtension - determines if an extension name is supported
C SPECIFICATION
GLboolean gluCheckExtension(const GLubyte * extName,
const GLubyte * extString);
PARAMETERS
extName
Specifies an extension name.
extString
Specifies a space-separated list of extension names supported.
DESCRIPTION
gluCheckExtension returns GLU_TRUE if extName is supported otherwise
GLU_FALSE is returned.
This is used to check for the presence for OpenGL, GLU, or GLX
extension names by passing the extension strings returned by
glGetString(), gluGetString(), glXGetClientString(),
glXQueryExtensionsString(), or glXQueryServerString(), respectively, as
extString.
NOTES
Cases where one extension name is a substring of another are correctly
handled.
There may or may not be leading or trailing blanks in extString.
Extension names should not contain embedded spaces.
All strings are null-terminated.
