NAMEwcscoll — compare wide strings according to current collation
LIBRARYStandard C Library (libc, -lc)
SYNOPSIS#include < wchar.h>
wcscoll( const wchar_t *s1, const wchar_t *s2);
DESCRIPTIONThe wcscoll() function compares the null-terminated strings s1 and s2 according to the current locale collation order. In the “
C” locale, wcscoll() is equivalent to wcscmp().
RETURN VALUESThe 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.
ERRORSThe wcscoll() function will fail if:
- [ EILSEQ]
- An invalid wide character code was specified.
- [ ENOMEM]
- Cannot allocate enough memory for temporary buffers.
STANDARDSThe wcscoll() function conforms to ISO/IEC 9899:1999 (“ISO C99”).
BUGSThe current implementation of wcscoll() only works in single-byte LC_CTYPE locales, and falls back to using wcscmp() in locales with extended character sets.
