For use with the -qtempinc compiler option, supplies the name of the file containing the template definitions corresponding to the template declarations contained in a header file.
This pragma is not normally required if your template implementation file has the same name as the header file containing the template declarations, and a .c extension. You only need to use the pragma if the template implementation file does not conform to this file-naming convention. For more information about using template implementation files, see Using C++ templates
#pragma implementation is only effective if the -qtempinc option is in effect. Otherwise, the pragma has no meaning and is ignored.
The pragma can appear in the header file containing the template declarations, or in a source file that includes the header file. It can appear anywhere that a declaration is allowed.
