MPI_File_write_shared - Writes a file using the shared file pointer
(blocking, noncollective).
C Syntax
#include <mpi.h>
int MPI_File_write_shared(MPI_File fh, void *buf, int count,
MPI_Datatype datatype, MPI_Status *status)
INCLUDE ’mpif.h’
MPI_FILE_WRITE_SHARED(FH, BUF, COUNT, DATATYPE, STATUS, IERROR)
<type> BUF(*)
INTEGER FH, COUNT, DATATYPE, STATUS(MPI_STATUS_SIZE),
IERROR
#include <mpi.h>
void MPI::File::Write_shared(const void* buf, int count,
const MPI::Datatype& datatype, MPI::Status& status)
void MPI::File::Write_shared(const void* buf, int count,
const MPI::Datatype& datatype)
- fh
- File handle (handle).
- buf
- Initial address of buffer (choice).
- count
- Number of elements in buffer (integer).
- datatype
- Data type of each buffer element (handle).
- status
- Status object (status).
- IERROR
- Fortran only: Error status (integer).
MPI_File_write_shared
is a blocking routine that uses the shared file pointer to write files.
The order of serialization is not deterministic for this noncollective
routine.
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.
