MPI_Status_set_cancelled(3OpenMPI)										MPI_Status_set_cancelled(3OpenMPI)

NAME

       MPI_Status_set_cancelled - Sets status to indicate a request has been canceled.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Status_set_cancelled(MPI_Status *status, int flag)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_STATUS_SET_CANCELLED(STATUS, FLAG, IERROR)
	    INTEGER   STATUS(MPI_STATUS_SIZE), IERROR
	    LOGICAL FLAG

C++ Syntax
       #include <mpi.h>
       void MPI::Status::Set_cancelled(bool flag)

INPUT
/OUTPUT PARAMETER
       status	 Status with which to associate cancel flag (status).

INPUT PARAMETER

       flag	 If true, indicates request was canceled (logical).

OUTPUT PARAMETER

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       If  flag  is set to true, then a subsequent call to MPI_Test_cancelled(status, flag) will also return flag = true; otherwise it will return
       false.

NOTES

       Users are advised not to reuse the status fields for values other than those for which they were intended. Doing so may lead to	unexpected
       results	when  using the status object. For example, calling MPI_Get_elements may cause an error if the value is out of range, or it may be
       impossible to detect such an error. The extra_state argument provided with a generalized request can be used  to  return  information  that
       does  not  logically  belong  in status. Furthermore, modifying the values in a status set internally by MPI, such as MPI_Recv, may lead to
       unpredictable results and is strongly discouraged.

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. By default, this error handler aborts the MPI job, except  for
       I/O  function  errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be
       used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
