| FUNCTION |
| <<wcscasecmp>>---case-insensitive wide character string compare |
| |
| INDEX |
| wcscasecmp |
| |
| ANSI_SYNOPSIS |
| #include <wchar.h> |
| int wcscasecmp(const wchar_t *<[a]>, const wchar_t *<[b]>); |
| |
| TRAD_SYNOPSIS |
| #include <wchar.h> |
| int wcscasecmp(<[a]>, <[b]>) |
| wchar_t *<[a]>; |
| wchar_t *<[b]>; |
| |
| DESCRIPTION |
| <<wcscasecmp>> compares the wide character string at <[a]> to |
| the wide character string at <[b]> in a case-insensitive manner. |
| |
| RETURNS |
| |
| If <<*<[a]>>> sorts lexicographically after <<*<[b]>>> (after |
| both are converted to uppercase), <<wcscasecmp>> returns a |
| number greater than zero. If the two strings match, |
| <<wcscasecmp>> returns zero. If <<*<[a]>>> sorts |
| lexicographically before <<*<[b]>>>, <<wcscasecmp>> returns a |
| number less than zero. |
| |
| PORTABILITY |
| POSIX-1.2008 |
| |
| <<wcscasecmp>> requires no supporting OS subroutines. It uses |
| tolower() from elsewhere in this library. |
