| .SH NAME |
| wcsncpy \- copy a fixed-size string of wide characters |
| .SH SYNOPSIS |
| .nf |
| .B #include <wchar.h> |
| .sp |
| .BI "wchar_t *wcsncpy(wchar_t *" dest ", const wchar_t *" src ", size_t " n ); |
| .fi |
| .SH DESCRIPTION |
| The |
| .BR wcsncpy () |
| function is the wide-character equivalent of the |
| .BR strncpy (3) |
| function. |
| It copies at most \fIn\fP wide characters from the wide-character |
| string pointed to by \fIsrc\fP, |
| including the terminating L\(aq\\0\(aq character, |
| to the array pointed to by \fIdest\fP. |
| Exactly \fIn\fP wide characters are |
| written at \fIdest\fP. |
| If the length \fIwcslen(src)\fP is smaller than \fIn\fP, |
| the remaining wide characters in the array |
| pointed to by \fIdest\fP are filled |
| with L\(aq\\0\(aq characters. |
| If the length \fIwcslen(src)\fP is greater or equal |
| to \fIn\fP, the string pointed to by \fIdest\fP |
| will not be L\(aq\\0\(aq terminated. |
| .PP |
| The strings may not overlap. |
| .PP |
| The programmer must ensure that there is room for at least \fIn\fP wide |
| characters at \fIdest\fP. |
| .SH "RETURN VALUE" |
| .BR wcsncpy () |
| returns \fIdest\fP. |
