NAME¶
MPI_File_iwrite - Nonblocking write using individual file pointer
SYNOPSIS¶
#ifdef HAVE_MPI_GREQUEST
#include "mpiu_greq.h"
#endif
int MPI_File_iwrite(MPI_File fh, ROMIO_CONST void *buf, int count,
MPI_Datatype datatype, MPI_Request *request)
- fh
- - file handle (handle)
- 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.
