MPI_File_read_at_all_begin_c(3) MPI MPI_File_read_at_all_begin_c(3)
NAME
MPI_File_read_at_all_begin_c - Begin a split collective read using
explicit offset
SYNOPSIS
int MPI_File_read_at_all_begin_c(MPI_File fh, MPI_Offset offset, void *buf,
MPI_Count count, MPI_Datatype datatype)
INPUT PARAMETERS
fh - file handle (handle)
offset - file offset (nonnegative integer)
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. 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.
