_strninc, _wcsninc, _mbsninc, _mbsninc_l

  • Grein

Advances a string pointer by n characters.

Important

_mbsninc and _mbsninc_l cannot be used in applications that execute in the Windows Runtime. For more information, see CRT functions not supported in Universal Windows Platform apps.

Syntax

char *_strninc(
   const char *str,
   size_t count
);
wchar_t *_wcsninc(
   const wchar_t *str,
   size_t count
);
unsigned char *_mbsninc(
   const unsigned char *str,
   size_t count
);
unsigned char *_mbsninc(
   const unsigned char *str,
   size_t count,
   _locale_t locale
);

Parameters

str
Source string.

count
Number of characters to increment a string pointer.

locale
Locale to use.

Return value

Each of these routines returns a pointer to str after str has been incremented by count characters or NULL if the supplied pointer is NULL. If count is greater than or equal to the number of characters in str, the result is undefined.

Remarks

The _mbsninc function increments str by count multibyte characters. _mbsninc recognizes multibyte-character sequences according to the multibyte code page currently in use.

By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT.

Generic-text routine mappings

Tchar.h routine _UNICODE and _MBCS not defined _MBCS defined _UNICODE defined
_tcsninc _strninc _mbsninc _wcsninc

_strninc and _wcsninc are single-byte-character string and wide-character string versions of _mbsninc. _wcsninc and _strninc are provided only for this mapping and shouldn't be used otherwise. For more information, see Using generic-text mappings and Generic-text mappings.

_mbsninc_l is identical except that it uses the locale parameter passed in instead. For more information, see Locale.

Requirements

Routine Required header
_mbsninc <mbstring.h>
_mbsninc_l <mbstring.h>
_strninc <tchar.h>
_wcsninc <tchar.h>
