NAME
MPI_File_read_shared - Reads a file using the shared file pointer
(blocking, noncollective).
SYNTAX
C Syntax
#include <mpi.h>
int MPI_File_read_shared(MPI_File fh, void *buf, int count,
MPI_Datatype datatype, MPI_Status *status)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_FILE_READ_SHARED(FH, BUF, COUNT, DATATYPE, STATUS,
IERROR)
<TYPE> BUF(*)
INTEGER FH, COUNT, DATATYPE,
STATUS(MPI_STATUS_SIZE), IERROR
C++ Syntax
#include <mpi.h>
void MPI::File::Read_shared(void* buf, int count,
const MPI::Datatype& datatype, MPI::Status& status)
void MPI::File::Read_shared(void* buf, int count,
const MPI::Datatype& datatype)
INPUT/OUTPUT PARAMETER
fh File handle (handle).
INPUT PARAMETERS
count Number of elements in buffer (integer)
datatype Data type of each buffer element (handle).
OUTPUT PARAMETERS
buf Initial address of buffer (choice).
status Status object (status).
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_File_read_shared is a blocking routine that uses the shared file
pointer to read files. The order of serialization is not deterministic
for this noncollective routine.
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++ func-
tions do not return errors. If the default error handler is set to
MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
