Synopsis
PCint pcQueryExtension(
PCstring extensionName
);
Parameters
extensionName The name of an extension entry point.
Returns
True (non-zero) if the extension named by the extensionName parameter is present in the

Description
This function tests if an extension is available in the current Library implementation.
Each extension to the Library has a name (see Appendix B (page 75) in the Parallel Compositing

Library, the function returns true. If the extension is not supported or is not a valid extension
name, the function returns false.
