Routine Mappings

The generic-text routine mappings are defined in TCHAR.H. _tccpy and _tclen map to functions in the MBCS model; they are mapped to macros or inline functions in the SBCS and Unicode models for completeness. For information on a generic text routine, see the help topic about the corresponding SBCS-, _MBCS-, or _UNICODE-related routine.

More specific information about individual routines listed in the left column below is not available in this documentation. However, you can easily look up the information on a corresponding SBCS-, _MBCS-, or _UNICODE-related routine. Use the Search command on the Help menu to look up any generic-text routine listed below.

For related information, see Generic-Text Mappings in TCHAR.H.
