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 \0.

       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 \0.
