fmt_uint0 - Man Page

write a zero-padded ASCII representation of an unsigned integer


#include <fmt.h>

size_t fmt_uint0(char *dest,unsigned int source,
                      size_t n);


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.
