man fmt_uint0 () - write a zero-padded ASCII representation of an unsigned integer
NAME
fmt_uint0 - write a zero-padded ASCII representation of an unsigned integer
SYNTAX
#include <fmt.h>
unsigned int fmt_uint0(char *dest,unsigned int source, unsigned int n);
DESCRIPTION
fmt_uint0 writes an ASCII representation ('0' to '9', base 10) of source to dest and returns the number of bytes written. The output is padded with '0'-bytes until it encompasses at least n bytes, but it will not be truncated if it does not fit.
fmt_uint0 does not append \0.
If dest 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.
