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 in the following table 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.
