| .SH NAME |
| wmemcmp \- compare two arrays of wide-characters |
| .SH SYNOPSIS |
| .nf |
| .B #include <wchar.h> |
| .PP |
| .BI "int wmemcmp(const wchar_t *" s1 ", const wchar_t *" s2 ", size_t " n ); |
| .fi |
| .SH DESCRIPTION |
| The |
| .BR wmemcmp () |
| function is the wide-character equivalent of the |
| .BR memcmp (3) |
| function. |
| It compares the |
| .IR n |
| wide-characters starting at |
| .I s1 |
| and the |
| .I n |
| wide-characters starting at |
| .IR s2 . |
| .SH RETURN VALUE |
| The |
| .BR wmemcmp () |
| function returns |
| zero if the wide-character arrays of size |
| .I n |
| at |
| .IR s1 |
| and |
| .I s2 |
| are equal. |
| It returns an integer greater than |
| zero if at the first differing position |
| .I i |
| .RI ( i " <" |
| .IR n ), |
| the |
| corresponding wide-character |
| .I s1[i] |
| is greater than |
| .IR s2[i] . |
| It returns an integer less than zero if |
| at the first differing position |
| .I i |
| .RI ( i |
| < |
| .IR n ), |
| the corresponding |
| wide-character |
| .I s1[i] |
| is less than |
| .IR s2[i] . |
