сравнить две строки широких символов фиксированного размера (compare two fixed-size wide-character strings)
Имя (Name)
wcsncmp - compare two fixed-size wide-character strings
Синопсис (Synopsis)
#include <wchar.h>
int wcsncmp(const wchar_t *s1, const wchar_t *s2, size_t n);
Описание (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.
Возвращаемое значение (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].
