int
wcscoll
(const
wchar_t *s1, const
wchar_t *s2);
wcscoll
() function compares the nul-terminated
strings s1 and s2 according to the
current locale collation order. In the
“C
” locale,
wcscoll
() is equivalent to
wcscmp
().
wcscoll
() function returns an integer greater than,
equal to, or less than 0, if s1 is greater than, equal
to, or less than s2.
No return value is reserved to indicate errors; callers should set
errno to 0 before calling
wcscoll
(). If it is non-zero upon return from
wcscoll
(), an error has occurred.
wcscoll
() function will fail if:
wcscoll
() function conforms to
ISO/IEC 9899:1999 (“ISO C99”).
wcscoll
() function
disregards LC_COLLATE
locales, and falls back to using
the wcscmp
() function.
