The present implementation of the Event Management framework has the limitations described below. For a more up-to-date list of limitations, refer to the README file on EMan in the SOMobjects Developer Toolkit.

• EMan supports registering a maximum of 64 AIX message queues.

• EMan can only wait on file descriptors (including files, pipes, sockets, and message queues) on AIX, and socket identifiers on OS/2.

• EMan supports registering a maximum of FILENO (the AIX limit on maximum number of open files) file descriptors on AIX, and FD_SETSIZE socket identifiers on OS/2 (FD_SETSIZE is defined by the TCP/IP product).
