MPI_Status_f082f, MPI_Status_c2f08 - Translates a Fortran 2008 status into a Fortran INTEGER-style status, or vice versa.

## 18.2.338.1. SYNTAX

### 18.2.338.1.1. C Syntax

    #include <mpi.h>

    int MPI_Status_f082f(const MPI_F08_status *f08_status, MPI_Fint *f_status)
    int MPI_Status_f2f08(const MPI_Fint *f_status, MPI_F08_status *f08_status)

### 18.2.338.1.2. Fortran mpi Module Syntax

    USE MPI

    MPI_STATUS_F082F(F08_STATUS, F_STATUS, IERROR)
        TYPE(MPI_Status) :: F08_STATUS
        INTEGER :: STATUS(MPI_STATUS_SIZE), IERROR

    MPI_STATUS_F2F08(F_STATUS, F08_STATUS, IERROR)
        INTEGER :: F_STATUS(MPI_STATUS_SIZE), IERROR
        TYPE(MPI_Status) :: F08_STATUS

### 18.2.338.1.3. Fortran mpi_f08 Module Syntax

    USE mpi_f08

    MPI_Status_f082f(f08_status, f_status, ierror)
        TYPE(MPI_Status), INTENT(IN) :: f08_status
        INTEGER, INTENT(OUT) :: f_status(MPI_STATUS_SIZE)
        INTEGER, OPTIONAL, INTENT(OUT) :: ierror

    MPI_Status_f2f08(f_status, f08_status, ierror)
        INTEGER, INTENT(IN) :: f_status(MPI_STATUS_SIZE)
        TYPE(MPI_Status), INTENT(OUT) :: f08_status
        INTEGER, OPTIONAL, INTENT(OUT) :: ierror

## 18.2.338.2. PARAMETERS

- `f08_status` : mpi_f08-style MPI status object

- `f_status` : mpi-style INTEGER MPI status object

## 18.2.338.3. DESCRIPTION

These two procedures are provided to convert from a Fortran 2008 status (which is a derived datatype made of integers) to a Fortran status (which is an array of integers), 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_f082f, if `f08_status` is a valid Fortran status, but not the Fortran value of `MPI_F08_STATUS_IGNORE` (in C), `MPI_STATUS_IGNORE` (in Fortran) or `MPI_F08_STATUSES_IGNORE` (in C) or `MPI_STATUSES_IGNORE` (in Fortran), then MPI_Status_f082f returns in `f_status` a valid array with the same content. If `f08_status` is the C value of `MPI_F08_STATUS_IGNORE` or `MPI_F08_STATUSES_IGNORE` or 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_f2f08, the opposite conversion is applied. If `f_status` is `MPI_STATUS_IGNORE` or `MPI_STATUSES_IGNORE`, or if `f_status` is not a valid Fortran 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.

## 18.2.338.4. NOTES

The Fortran subroutines for these MPI routines are only available in the mpi and mpi_f08 modules (including the type specification for `TYPE(MPI_Status)`; they are (intentionally) not available in `mpif.h`.
