  13 DESCRIPTION
  14      The Pfdinfo_iter() function iterates over the open files in the process
  15      represented by P.
  16 
  17      For each open file, the callback function func will be invoked and it
  18      will be passed the data argument as well as a pointer to a prfdinfo_t
  19      structure defined in libproc(3LIB).  For the full signature of the
  20      proc_fdinfo_f see libproc(3LIB).
  21 
  22      The return value of func controls whether or not iteration continues.  If
  23      func returns 0, then iteration will continue.  However, if func instead
  24      returns a non-zero value, then iteration will halt and that value will be
  25      used as the return value of the Pfdinfo_iter() function.  Because the
  26      Pfdinfo_iter() function returns -1 to an indicate its own errors, it is
