_mbsspnp, _mbsspnp_l, _strspnp, _wcsspnp

Returns a pointer to the first character in a given string that is not in another given string.

unsigned char *_mbsspnp(
   const unsigned char *str,
   const unsigned char *charset
);
unsigned char *_mbsspnp_l(
   const unsigned char *str,
   const unsigned char *charset,
   _locale_t locale
);
char *_strspnp(
   const char *str,
   const char *charset
);
wchar_t *_wcsspnp(
   const unsigned wchar_t *str,
   const unsigned wchar_t *charset
);

Parameters

  • str
    Null-terminated string to search.

  • charset
    Null-terminated character set.

  • locale
    Locale to use.

Return Value

_strspnp, _wcsspnp, and _mbsspnp return a pointer to the first character in str that does not belong to the set of characters in charset*.* Each of these functions returns NULL if str consists entirely of characters from charset*.* For each of these routines, no return value is reserved to indicate an error.

Remarks

The _mbsspnp function returns a pointer to the multibyte character that is the first character in str that does not belong to the set of characters in charset. _mbsspnp recognizes multibyte-character sequences according to the multibyte code page currently in use. The search does not include terminating null characters.

If either str or charset is a null pointer, this function invokes the invalid parameter handler, as described in Parameter Validation. If execution is allowed to continue, the function returns NULL and sets errno to EINVAL.

_strspnp and _wcsspnp are single-byte character and wide-character versions of _mbsspnp. _strspnp and _wcsspnp behave identically to _mbsspnp otherwise; they are provided only for this mapping and should not be used for any other reason. For more information, see Using Generic-Text Mappings and Generic-Text Mappings.

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