  1. .TH fmt_uint0 3
  2. .SH NAME
  3. fmt_uint0 \- write a zero-padded ASCII representation of an unsigned integer
  4. .SH SYNTAX
  5. .B #include <libowfat/fmt.h>
  6. size_t \fBfmt_uint0\fP(char *\fIdest\fR,unsigned int \fIsource\fR,
  7. size_t \fIn\fR);
  8. .SH DESCRIPTION
  9. fmt_uint0 writes an ASCII representation ('0' to '9', base 10) of
  10. \fIsource\fR to \fIdest\fR and returns the number of bytes written.
  11. The output is padded with '0'-bytes until it encompasses at least
  12. \fIn\fR bytes, but it will not be truncated if it does not fit.
  13. fmt_uint0 does not append \\0.
  14. If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_uint0 returns the number
  15. of bytes it would have written.
  16. For convenience, fmt.h defines the integer FMT_ULONG to be big enough to
  17. contain every possible fmt_uint output plus \\0.
