int MPI_File_close(MPI_File *fh)
MPI_FILE_CLOSE(FH, IERROR)INTEGER FH, IERROR
int MPI::File::Close()
void
MPI_FILE_CLOSE first synchronizes file state (equivalent to performing an MPI_FILE_SYNC), then closes the file associated with fh. The file is deleted if it was opened with access mode MPI_MODE_DELETE_ON_CLOSE (equivalent to performing an MPI_FILE_DELETE). MPI_FILE_CLOSE is a collective routine.
The user is responsible for ensuring that all outstanding nonblocking requests and split collective operations associated with fh made by a process have completed before that process calls MPI_FILE_CLOSE.
The MPI_FILE_CLOSE routine deallocates the file handle object and sets fh to MPI_FILE_NULL.
