** FUNCTION: PR_Select
|
|
** DESCRIPTION:
|
|
**
|
|
** The call returns as soon as I/O is ready on one or more of the underlying
|
|
** file/socket descriptors or an exceptional condition is pending. A count of the
|
|
** number of ready descriptors is returned unless a timeout occurs in which case
|
|
** zero is returned. On return, PR_Select replaces the given descriptor sets with
|
|
** subsets consisting of those descriptors that are ready for the requested condition.
|
|
** The total number of ready descriptors in all the sets is the return value.
|
|
**
|
|
** INPUTS:
|
|
** PRInt32 num
|
|
** This argument is unused but is provided for select(unix) interface
|
|
** compatability. All input PR_fd_set arguments are self-describing
|
|
** with its own maximum number of elements in the set.
|
|
**
|
|
** PR_fd_set *readfds
|
|
** A set describing the io descriptors for which ready for reading
|
|
** condition is of interest.
|
|
**
|
|
** PR_fd_set *writefds
|
|
** A set describing the io descriptors for which ready for writing
|
|
** condition is of interest.
|
|
**
|
|
** PR_fd_set *exceptfds
|
|
** A set describing the io descriptors for which exception pending
|
|
** condition is of interest.
|
|
**
|
|
** Any of the above readfds, writefds or exceptfds may be given as NULL
|
|
** pointers if no descriptors are of interest for that particular condition.
|
|
**
|
|
** PRIntervalTime timeout
|
|
** Amount of time the call will block waiting for I/O to become ready.
|
|
** If this time expires without any I/O becoming ready, the result will
|
|
** be zero.
|
|
**
|
|
** OUTPUTS:
|
|
** PR_fd_set *readfds
|
|
** A set describing the io descriptors which are ready for reading.
|
|
**
|
|
** PR_fd_set *writefds
|
|
** A set describing the io descriptors which are ready for writing.
|
|
**
|
|
** PR_fd_set *exceptfds
|
|
** A set describing the io descriptors which have pending exception.
|
|
**
|
|
** RETURN:PRInt32
|
|
** Number of io descriptors with asked for conditions or zero if the function
|
|
** timed out or -1 on failure. The reason for the failure is obtained by
|
|
** calling PR_GetError().
|
|
** XXX can we implement this on windoze and mac?
