26 function copies at most \fIn\fP characters from the string
27 pointed to by \fIsrc\fP, including the terminating \(aq\\0\(aq character,
28 to the array pointed to by \fIdest\fP.
29 Exactly \fIn\fP characters are written at
31 If the length \fIstrlen(src)\fP is smaller than \fIn\fP, the
32 remaining characters in the array pointed to by \fIdest\fP are filled
33 with \(aq\\0\(aq characters.
34 If the length \fIstrlen(src)\fP is greater or equal to
35 \fIn\fP, the string pointed to by \fIdest\fP will
36 not be \(aq\\0\(aq terminated.
38 The strings may not overlap.
40 The programmer must ensure that there is room for at least \fIn\fP characters
44 returns a pointer to the terminating null
45 in \fIdest\fP, or, if \fIdest\fP is not null-terminated,
