count | list length (integer)

array_of_requests | array of requests (array of handles)

index | index of operation that completed, or MPI_UNDEFINED if none
completed (integer)

flag | true if one of the operations is complete (logical)

status | status object (Status). May be MPI_STATUS_NULL.

All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type INTEGER in Fortran.
All MPI routines (except MPI_Wtime and MPI_Wtick) return an error value; C routines as the value of the function and Fortran routines in the last argument. Before the value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job. The error handler may be changed with MPI_Errhandler_set; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarentee that an MPI program can continue past an error.
