NAME
       MPI_Status_f2c, MPI_Status_c2f  - Translates a C status into a Fortran status, or vice versa.

SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Status_f2c(MPI_Fint *f_status, MPI_Status *c_status)
       int MPI_Status_c2f(MPI_Status *c_status, MPI_Fint *f_status)

DESCRIPTION
       These  two  procedures  are provided in C to convert from a Fortran status (which is an array of integers) to a C status (which is a struc-
       ture), and vice versa. The conversion occurs on all the information in status, including that which is hidden. That is, no status  informa-
       tion is lost in the conversion.

       When  using  MPI_Status_f2c,  if f_status is a valid Fortran status, but not the Fortran value of MPI_STATUS_IGNORE or MPI_STATUSES_IGNORE,
       then MPI_Status_f2c returns in c_status a valid C status with the same content. If f_status is the Fortran value  of  MPI_STATUS_IGNORE	or
       MPI_STATUSES_IGNORE, or if f_status is not a valid Fortran status, then the call is erroneous.

       When  using  MPI_Status_c2f, 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 C status has the same source, tag and error code values as the Fortran status, and returns the same answers	when  queried  for  count,
       elements,  and  cancellation.  The  conversion  function may be called with a Fortran status argument that has an undefined error field, in
       which case the value of the error field in the C status argument is undefined.
