.SH NAME
|

|
|
|
fmt_long \- write an ASCII representation of a long integer
|
|
|
|
|
.SH SYNTAX
|
|
|
|
|
.B #include <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.
