  1. .TH fmt_ulong0 3
  2. .SH NAME
  3. fmt_ulong0 \- write a zero-padded ASCII representation of an unsigned long integer
  5. .B #include <fmt.h>
  6. size_t \fBfmt_ulong0\fP(char *\fIdest\fR, unsigned long \fIsource\fR,
  7. size_t \fIn\fR);
  9. fmt_ulong0 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_ulong0 does not append \\0.
  14. If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_ulong0 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_ulong output plus \\0.
  18. .SH "SEE ALSO"
  19. scan_ulong(3), fmt_ulong(3)
