NAME
       fmt_ulong0 - write a zero-padded ASCII representation of an unsigned long integer

SYNTAX
       #include <fmt.h>

       size_t fmt_ulong0(char *dest, unsigned long source,
			       size_t n);

DESCRIPTION
       fmt_ulong0  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_ulong0 does not append .

       If dest equals FMT_LEN (i.e. is zero), fmt_ulong0 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_ulong output plus .
