.SH NAME
|
|

|
|
.SH SYNTAX
|
|
.B #include <fmt.h>
|
|
|
|
size_t \fBfmt_str\fP(char *\fIdest\fR,const char *\fIsource\fR);
|
|
.SH DESCRIPTION
|
|
fmt_str copies all 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_str returns the number
|
|
of bytes it would have written, i.e. the number of leading nonzero bytes
|
|
of \fIsource\fR.
