NAME
MPI_File_write_ordered_end - Writes a file at a location specified by a shared file pointer; ending part of a split collective routine (blocking).SYNTAX
C Syntax #include <mpi.h> int MPI_File_write_ordered_end(MPI_File fh, void *buf, MPI_Status *status) Fortran Syntax INCLUDE 'mpif.h' MPI_FILE_WRITE_ORDERED_END(FH, BUF, STATUS, IERROR) <type> BUF(*) INTEGER FH, STATUS(MPI_STATUS_SIZE), IERROR
C++ Syntax
#include <mpi.h> void MPI::File::Write_ordered_end(const void* buf, MPI::Status& status) void MPI::File::Write_ordered_end(const void* buf)
INPUT/OUTPUT PARAMETER
- fh
- File handle (handle).
INPUT PARAMETER
- buf
- Initial address of buffer (choice).
OUTPUT PARAMETERS
- status
- Status object (status).
- IERROR
- Fortran only: Error status (integer).
DESCRIPTION
MPI_File_write_ordered_end is the ending part of a split collective routine that must be called by all processes in the communicator group associated with the file handle fh. MPI_File_write_ordered_end returns the number of elements written into the file associated with fh in status.NOTES
All the nonblocking collective routines for data access are "split" into two routines, each with _begin or _end as a suffix. These split collective routines are subject to the semantic rules described in Section 9.4.5 of the MPI-2 standard.ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI:Exception object.Before the error value is returned, the current MPI error handler is called. For MPI I/O function errors, the default error handler is set to MPI_ERRORS_RETURN. The error handler may be changed with MPI_File_set_errhandler; the predefined error handler MPI_ERRORS_ARE_FATAL may be used to make I/O errors fatal. Note that MPI does not guarantee that an MPI program can continue past an error.
