          int MPI_Status_f082c(const MPI_F08_status *f08_status, MPI_Status *c_status)
          int MPI_Status_c2f08(const MPI_Status *c_status, MPI_F08_status *f08_status)

PARAMETERS

       • f08_status : mpi_f08-style MPI status object

       • c_status : C-style MPI status object

DESCRIPTION

       These  two  procedures  are  provided in C to convert from a Fortran 2008 status (which is a derived type
       made of integers) to a C status (which is a structure), and vice versa. The conversion occurs on all  the
       information  in  status,  including  that  which is hidden. That is, no status information is lost in the
       conversion.

       When using MPI_Status_f082c, if f08_status is a valid Fortran  status,  but  not  the  Fortran  value  of
       MPI_F08_STATUS_IGNORE  or  MPI_F08_STATUSES_IGNORE,  then  MPI_Status_f082c returns in c_status a valid C
       status  with  the  same  content.  If  f08_status  is  the  Fortran   value   of   MPI_STATUS_IGNORE   or
       MPI_STATUSES_IGNORE, or if f08_status is not a valid Fortran status, then the call is erroneous.

       When  using  MPI_Status_c2f08,  the  opposite  conversion is applied. If c_status is MPI_STATUS_IGNORE or
       MPI_STATUSES_IGNORE, or if c_status is not a valid C status, then the call is erroneous.

       The input status has the same source, tag and error code values as the output  status,  and  returns  the
       same  answers  when  queried for count, elements, and cancellation. The conversion function may be called
       with an input status argument that has an undefined error field, in which case the  value  of  the  error
       field in the output status argument is undefined.

NOTES

       These functions are only available in C; they are not available in any of the Fortran MPI interfaces.
