Each of these routines returns a pointer to the character that immediately follows current.

Заметки

The _mbsinc function returns a pointer to the first byte of the multibyte character that immediately follows current. _mbsinc recognizes multibyte-character sequences according to the multibyte code page currently in use, while _mbsinc_l is identical except that it uses the locale parameter passed in instead. For more information, see Locale.

The generic-text function _tcsinc, defined in Tchar.h, maps to _mbsinc if _MBCS has been defined or to _wcsinc if _UNICODE has been defined. Otherwise _tcsinc maps to _strinc. _strinc and _wcsinc are single-byte character and wide-character versions of _mbsinc. _strinc and _wcsinc are provided only for this mapping and should not be used otherwise. For more information, see Using Generic-Text Mappings and Generic-Text Mappings.

If current is NULL, the invalid parameter handler is invoked, as described in Parameter Validation. If execution is allowed to continue, this function returns EINVAL and sets errno to EINVAL.

Security Note This API incurs a potential threat brought about by a buffer overrun problem. Buffer overrun problems are a frequent method of system attack, resulting in an unwarranted elevation of privilege. For more information, see Avoiding Buffer Overruns.
