NAME¶

MPI_File_write_at_all_c - Collective write using explicit offset

SYNOPSIS¶

int MPI_File_write_at_all_c(MPI_File fh, MPI_Offset offset, ROMIO_CONST void *buf,
MPI_Count count, MPI_Datatype datatype, MPI_Status * status)

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¶

status

- status object (Status)

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.
