.TH fmt_uint0 3
|
|
.SH NAME
|
|
fmt_uint0 \- write a zero-padded ASCII representation of an unsigned integer
|
|
.SH SYNTAX
|
|
.B #include <libowfat/fmt.h>
|
|
|
|
size_t \fBfmt_uint0\fP(char *\fIdest\fR,unsigned int \fIsource\fR,
|
|
size_t \fIn\fR);
|
|
.SH DESCRIPTION
|
|
fmt_uint0 writes an ASCII representation ('0' to '9', base 10) of
|
|
\fIsource\fR to \fIdest\fR and returns the number of bytes written.
|
|
The output is padded with '0'-bytes until it encompasses at least
|
|
\fIn\fR bytes, but it will not be truncated if it does not fit.
|
|
|
|
fmt_uint0 does not append \\0.
|
|
|
|
If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_uint0 returns the number
|
|
of bytes it would have written.
|
|
|
|
For convenience, fmt.h defines the integer FMT_ULONG to be big enough to
|
|
contain every possible fmt_uint output plus \\0.
