C binding
int MPI_File_get_size(MPI_File fh, MPI_Offset *size)
Fortran 2008 binding
MPI_File_get_size(fh, size, ierror)
TYPE(MPI_File), INTENT(IN) :: fh
INTEGER(KIND=MPI_OFFSET_KIND), INTENT(OUT) :: size
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
Fortran binding
MPI_FILE_GET_SIZE(FH, SIZE, IERROR)
INTEGER FH, IERROR
INTEGER(KIND=MPI_OFFSET_KIND) SIZE
MPI_FILE_GET_SIZE returns, in size,
the current size in bytes
of the file associated with the file handle fh.
As far as consistency semantics are concerned,
MPI_FILE_GET_SIZE is a data access operation
(see Section File Consistency).
