| .SH NAME |
| wcsncmp \- compare two fixed-size wide-character strings |
| .SH SYNOPSIS |
| .nf |
| .B #include <wchar.h> |
| .sp |
| .BI "int wcsncmp(const wchar_t *" s1 ", const wchar_t *" s2 ", size_t " n ); |
| .fi |
| .SH DESCRIPTION |
| The |
| .BR wcsncmp () |
| function is the wide-character equivalent of the |
| .BR strncmp (3) |
| function. |
| It compares the wide-character string pointed to by \fIs1\fP and the |
| wide-character string pointed to by \fIs2\fP, but at most \fIn\fP wide |
| characters from each string. |
| In each string, the comparison extends only up |
| to the first occurrence of a L\(aq\\0\(aq character, if any. |
| .SH "RETURN VALUE" |
| The |
| .BR wcsncmp () |
| function returns zero if the wide-character strings at |
| \fIs1\fP and \fIs2\fP, truncated to at most length \fIn\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. |
