.SH DESCRIPTION
|
|
fmt_str copies at most \fImaxlen\fR leading nonzero bytes from
|
|
\fIsource\fR to \fIdest\fR and returns the number of bytes it copied.
|
|
|
|
fmt_str does not append \\0.
|
|

|
If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_strn returns the number
|
|
of bytes it would have written.
