MPI_File_iread(3) MPI MPI_File_iread(3)
NAME
MPI_File_iread - Nonblocking read using individual file pointer
SYNOPSIS
#ifdef HAVE_MPI_GREQUEST
#include "mpiu_greq.h"
#endif
int MPI_File_iread(MPI_File mpi_fh, void *buf, int count,
MPI_Datatype datatype, MPI_Request *request)
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)
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.
