  1. .TH fmt_longlong 3
  2. .SH NAME
  3. fmt_longlong \- write an ASCII representation of a long long integer
  4. .SH SYNTAX
  5. .B #include <libowfat/fmt.h>
  6. size_t \fBfmt_longlong\fP(char *\fIdest\fR,long long \fIsource\fR);
  7. .SH DESCRIPTION
  8. fmt_longlong writes an ASCII representation ('-' and '0' to '9', base 10) of
  9. \fIsource\fR to \fIdest\fR and returns the number of bytes written.
  10. fmt_longlong does not append \\0.
  11. If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_longlong returns the number
  12. of bytes it would have written.
  13. For convenience, fmt.h defines the integer FMT_LONG to be big enough to
  14. contain every possible fmt_longlong output plus \\0.
