Description
Unregisters a conversion type previously registered using RegisterConversionType.
Call UnregisterConversionType when a conversion type becomes unavailable. Typically, this function is called from the finalization section of a unit that implements the conversion type.
AType is the conversion type identifier for the type to unregister.
After a conversion type is unregistered, it is no longer listed by the GetConvTypes procedure. Calling the Convert function with an unregistered conversion type results in an EConversionError exception.
