mpi_file_get_size
MPI_File_get_size(3OpenMPI)MPI_File_get_size(3OpenMPI)NAME
MPI_File_get_size - Returns the current size of the file.
SYNTAX
C Syntax
#include <mpi.h>
int MPI_File_get_size(MPI_File fh, MPI_Offset *size)
Fortran Syntax (see FORTRAN 77 NOTES)
INCLUDE 'mpif.h'
MPI_FILE_GET_SIZE(FH, SIZE, IERROR)
INTEGER FH, ERROR
INTEGER(KIND=MPI_OFFSET_KIND) SIZE
C++ Syntax
#include <mpi.h>
MPI::Offset MPI::File::Get_size() const
INPUT PARAMETERS
fh File handle (handle).
size Size of the file in bytes (integer).
OUTPUT PARAMETER
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_File_get_size returns, in size , the current size in bytes of the file associated with the file handle fh. Note that the file size
returned by Solaris may not represent the number of bytes physically allocated for the file in those cases where all bytes in this file
have not been written at least once.
FORTRAN 77 NOTES
The MPI standard prescribes portable Fortran syntax for the SIZE argument only for Fortran 90. Sun FORTRAN 77 users may use the non-porta-
ble syntax
INTEGER*MPI_OFFSET_KIND SIZE
where MPI_ADDRESS_KIND is a constant defined in mpif.h and gives the length of the declared integer in bytes.
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
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.
