MPI_File_writeWrite using individual file pointer
int MPI_File_write(MPI_File fh, void *buf, int count, MPI_Datatype datatype, MPI_Status *status)
- file handle (handle)
- initial address of buffer (choice)
- number of elements in buffer (nonnegative integer)
- datatype of each buffer element (handle)
- status object (Status)
Notes for FortranAll 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.
