       MPI_Status_f2c  <#mpi-status-f2c>,  MPI_Status_f2c <#mpi-status-f2c> - Translates a C status into a Fortran
       INTEGER-style status, or vice versa.

SYNTAX
   C Syntax
	  #include <mpi.h>

	  int MPI_Status_f2c(const MPI_Fint *f_status, MPI_Status *c_status)
	  int MPI_Status_c2f(const MPI_Status *c_status, MPI_Fint *f_status)

PARAMETERS
       • f_status : mpi-style INTEGER MPI status object

       • c_status : C-style MPI status object

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 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_f2c <#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  <#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 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.
