                       MPIO_Request *request)

Input Parameters

fh

file handle (handle)

offset

file offset (nonnegative integer)

buf

initial address of buffer (choice)

count

number of elements in buffer (nonnegative integer)

datatype

datatype of each buffer element (handle)

Output Parameters

request

request object (handle)

Notes for Fortran

All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK) have an additional argument ierr at the end of the argument list. ierr is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked with the call statement.

All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type INTEGER in Fortran.
