See also

WIFEXITED, WEXITSTATUS, WIFSIGNALED, WTERMSIG, WIFSTOPPED for functions to manipulate status.

Job Control calls waitpid with WAIT_ANY (-1) and WNOHANG which means we can get a variety of results. The value returned is always a list of two elements.

  • If a child process has exited then waitpid returns (pid, status).

    If pid is not identified as a process in the list of known jobs then the Job Control code enters it into a stray pids table along with its status.

  • If no child process has exited then waitpid returns (0, status).

  • If waitpid errors then

    • If the error is ECHILD then either the pid doesn’t exist, is not a child process or the disposition of the SIGCHLD signal is SIG_IGN.

      However, waitpid can look at the stray pids table and see if the queried pid exists and return that PID and its status.

      Otherwise we return (0 #n).

    • If the result is EINTR we can loop, re-invoking waitpid.

    • Otherwise raise a ^system-error.

(rfd, wfd, rname, wname)

Otherwise the return value is the five element list:

(#f, #f, pipe-name, pipe-name, tmpdir)

poll predicates

The C/int C macros, POLLIN, POLLERR, etc., are managed as bitmasks in a C/short in poll(2)’s struct pollfd.

This is complicated because Idio doesn’t use a C/int of 0 (zero) as false and the C bitwise operators, C/&, etc., only operate on C/int types.

So a series of predicates exist which do the right thing, POLLIN? will test that the bit-field represented by the C macro, POLLIN is set in the C/short argument.

When registering a file descriptor or file handle you can pass a list of C/int values which will be OR-ed together into a C short. Later, the list of event results from poller-poll will have an revents value which you can test with these predicates:

fh := open-input-file ...
poller := libc/make-poller (list fh libc/POLLIN)
r := libc/poller-poll poller 1000

for p in r {
  fdh := ph p
  revents := pht p
  (cond
   ((libc/POLLERR? revents) {
      libc/poller-deregister poller fdh
    })
   ((libc/POLLIN? revents) {
      ...
    }))
}
