| .SH NAME |
| wmemcmp \- compare two arrays of wide-characters |
| .SH SYNOPSIS |
| .nf |
| .B #include <wchar.h> |
| .sp |
| .BI "int wmemcmp(const wchar_t *" s1 ", const wchar_t *" s2 ", size_t " n ); |
| .fi |
| .SH DESCRIPTION |
| The \fBwmemcmp\fP() function is the wide-character equivalent of the \fBmemcmp\fP() |
| function. It compares the \fIn\fP wide-characters starting at \fIs1\fP and the |
| \fIn\fP wide-characters starting at \fIs2\fP. |
| .SH "RETURN VALUE" |
| The \fBwmemcmp\fP() function returns zero if the wide-character arrays of size |
| \fIn\fP at \fIs1\fP and \fIs2\fP are equal. It returns an integer greater than |
| zero if at the first differing position \fIi\fP (\fIi\fP < \fIn\fP), the |
| corresponding wide-character \fIs1[i]\fP is greater than \fIs2[i]\fP. It |
| returns an integer less than zero if at the first differing position \fIi\fP |
| (\fIi\fP < \fIn\fP), the corresponding wide-character \fIs1[i]\fP is less than |
| \fIs2[i]\fP. |
