.SH NAME
stpncpy \- copy a fixed-size string, returning a pointer to its end
.SH SYNOPSIS
.SH DESCRIPTION
The
.BR stpncpy ()
-function copies at most \fIn\fP characters from the string
-pointed to by \fIsrc\fP, including the terminating null byte (\(aq\\0\(aq),
-to the array pointed to by \fIdest\fP.
-Exactly \fIn\fP characters are written at
-\fIdest\fP.
-If the length \fIstrlen(src)\fP is smaller than \fIn\fP, the
-remaining characters in the array pointed to by \fIdest\fP are filled
