_mbsnbicmp, _mbsnbicmp_l
Compares n bytes of two multibyte-character strings, ignoring case.
int _mbsnbicmp( const unsigned char *string1, const unsigned char *string2, size_t count );
The return value indicates the relationship between the substrings.
Return value | Description |
|---|---|
< 0 | string1 substring less than string2 substring. |
0 | string1 substring identical to string2 substring. |
> 0 | string1 substring greater than string2 substring. |
On an error, _mbsnbcmp returns _NLSCMPERROR, which is defined in String.h and Mbstring.h.
The _mbsnbicmp function lexicographically compares, at most, the first count bytes of string1 and string2. The comparison is performed without regard to case; _mbsnbcmp is a case-sensitive version of _mbsnbicmp. The comparison ends if a terminating null character is reached in either string before count characters are compared. If the strings are equal when a terminating null character is reached in either string before count characters are compared, the shorter string is lesser.
_mbsnbicmp is similar to _mbsnicmp, except that it compares strings by bytes instead of by characters.
Two strings containing characters located between 'Z' and 'a' in the ASCII table ('[', '\', ']', '^', '_', and '`') compare differently, depending on their case. For example, the two strings "ABCDE" and "ABCD^" compare one way if the comparison is lowercase ("abcde" > "abcd^") and the other way ("ABCDE" < "ABCD^") if it is uppercase.
_mbsnbicmp recognizes multibyte-character sequences according to the multibyte code page currently in use. It is not affected by the current locale setting.
If either string1 or string2 is a null pointer, _mbsnbicmp invokes the invalid parameter handler as described in Parameter Validation. If execution is allowed to continue, the function returns _NLSCMPERROR and sets errno to EINVAL.
