MPI_Status_f2c(3)                  Open MPI                  MPI_Status_f2c(3)



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 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, 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.
