NAME¶
wcsncmp - compare two fixed-size wide-character strings
SYNOPSIS¶
#include <wchar.h>
int wcsncmp(const wchar_t *s1, const wchar_t *s2, size_t n);
DESCRIPTION¶
The
wcsncmp() function is the wide-character equivalent of the
strncmp(3) function. It compares the wide-character string pointed to
by
s1 and the wide-character string pointed to by
s2, but at
most
n wide characters from each string. In each string, the comparison
extends only up to the first occurrence of a null wide character (L'\0'), if
any.
RETURN VALUE¶
The
wcsncmp() function returns zero if the wide-character strings at
s1 and
s2, truncated to at most length
n, are equal. It
returns an integer greater than zero if at the first differing position
i (
i <
n), the corresponding wide-character
s1[i] is greater than
s2[i]. It returns an integer less than
zero if at the first differing position
i (i <
n), the
corresponding wide-character
s1[i] is less than
s2[i].
ATTRIBUTES¶
Multithreading (see pthreads(7))¶
The
wcsncmp() function is thread-safe.
