Discussion

This function returns a number indicating the version of the Core Text framework. Note that framework version is not always an accurate indicator of feature availability. The recommended way to use this function is first to check that the function pointer is non-null, followed by calling it and comparing its result to a defined constant (or constants). For example, to determine whether the CoreText API is available:

if (&CTGetCoreTextVersion != NULL && CTGetCoreTextVersion() >= kCTVersionNumber10_5) {

 // CoreText API is available

Availability

Available in Mac OS X v10.5 and later.
