Description Elena Vengerova 2005-10-13 11:30:40 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050513 Fedora/1.7.8-2

Description of problem:
Calling of aio_read() before aio_write() on the socket leads to "in progress" state of both requests, whereas calling of aio_write() before aio_read() leads to successful completion of write request and "in progress" state of read request.


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Create pair of connected stream or datagram sockets.
2. Call aio_read() with correct buffer/length and none notification.
3. Call aio_write() with correct data/length and none notification.

  

Actual Results:  Data are not sent. aio_error() returns EINPROGRESS for both requests.

Expected Results:  Data should be sent, aio_error() should return 0 for write request and EINPROGRESS for read request.

The aio_* functions operate on files, not sockets, pipes, or whatever else.  The
implementation works correctly for files.
