POSIX Asynchronous IO

  1. POSIX Asynchronous IO

Status: No active volunteers.

RTEMS does not currently support POSIX Asynchronous IO as defined by OpenGroup?. These methods and associated constants are prototyped by the [ <aio.h>] header file which is cpukit/posix/include/aio.h in the RTEMS source tree. The following methods would have to be implemented:

All methods currently are implemented in RTEMS as stubs which return ENOSYS.

It is assumed that the implementation would have to have one or more server threads and these methods would interact with that server thread by enqueueing operation requests and checking on the completion status. The number of server threads along with characteristics such as stack size and priority would need to be application configurable.
