Advances a string pointer by n characters.

_mbsninc and _mbsninc_l cannot be used in applications that execute in the Windows Runtime. For more information, see CRT functions not supported with /ZW.

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.

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.

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

_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 should not 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.
