.TH fmt_long 3
.SH NAME
fmt_long \- write an ASCII representation of a long integer
.SH SYNTAX
.B #include <libowfat/fmt.h>

size_t \fBfmt_long\fP(char *\fIdest\fR,long \fIsource\fR);
.SH DESCRIPTION
fmt_long writes an ASCII representation ('-' and '0' to '9', base 10) of
\fIsource\fR to \fIdest\fR and returns the number of bytes written.

fmt_long does not append \\0.

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

For convenience, fmt.h defines the integer FMT_LONG to be big enough to
contain every possible fmt_long output plus \\0.
