FUNCTION |
<<wcscmp>>---compare two wide-character strings |
|
ANSI_SYNOPSIS |
#include <wchar.h> |
int wcscmp(const wchar_t *<[s1]>, *<[s2]>); |
|
TRAD_SYNOPSIS |
int wcscmp(<[s1]>, <[s2]> |
const wchar_t *<[s1]>, <[s2]>; |
|
DESCRIPTION |
The <<wcscmp>> function compares the wide-character string pointed to |
by <[s1]> to the wide-character string pointed to by <[s2]>. |
|
The sign of a non-zero return value is determined by the sign of the |
difference between the values of the first pair of wide-character codes |
that differ in the objects being compared. |
|
RETURNS |
Upon completion, <<wcscmp>> returns an integer greater than, equal to |
or less than 0, if the wide-character string pointed to by <[s1]> is |
greater than, equal to or less than the wide-character string pointed |
to by <[s2]> respectively. |
|
PORTABILITY |
<<wcscmp>> is ISO/IEC 9899/AMD1:1995 (ISO C). |
|
No supporting OS subroutines are required. |
