Synopsis

int MPI_File_read_ordered_begin(MPI_File fh, void *buf, int count, 
    MPI_Datatype datatype)

Input Parameters

fh: file handle (handle)

count: number of elements in buffer (nonnegative integer)

datatype: datatype of each buffer element (handle)

Output Parameters

buf: initial address of buffer (choice)

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. ierris 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 INTEGERin Fortran.
