NAME

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

SYNTAX

       #include <libowfat/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.
