MPI_Status_c2f(3)

NAME
MPI_Status_c2f - Convert a C MPI status object into a FORTRAN MPI status object

SYNOPSIS
#include <mpi.h>
int MPI_Status_c2f(MPI_Status *c_status, MPI_Fint *f_status);

#include <pmpi.h>
int PMPI_Status_c2f(MPI_Status *c_status, MPI_Fint *f_status);

INPUT PARAMETER
c_status
    - status object from C (structure)

OUTPUT PARAMETER
f_status
    - status object for FORTRAN (array)

DESCRIPTION
The MPI_Status_c2f() function is used to convert a C MPI_Status structure c_status, into a FORTRAN integer-array status object f_status. This function simply calls memcpy() with the correct size. PMPI_Status_c2f() is the profiling version of this function.

ERRORS
All MPI routines except for MPI_Wtime and MPI_Wtick return an error code. The the current MPI error handler is invoked if the return value is not MPI_SUCCESS. The default error handler aborts, but this may be changed with by using the MPI_Errhandler_set() function. The predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned instead. Note that MPI does not guarentee that an MPI program can continue past an error. In this implementation, all errors except MPI_ERR_INTERN or MPI_ERR_OTHER should always be recoverable. In C, the error code is passed as the return value. In FORTRAN, all functions have an parameter ierr which returns the error code. MPI C++ functions do not directly return an error code. However, C++ users may want to use the MPI::ERRORS_THROW_EXCEPTIONS handler. This will throw an MPI::Exception with the corresponding error code. To prevent exceptions from being raised from within C and Fortran code, they will see all error return values as MPI_ERR_PENDING when this handler is chosen. In this implementation, call MPI::throw_exception() to throw the correct exception if this occurs.
MPI_SUCCESS
    - No error;
MPI_ERR_PENDING
    - Pending exception;
MPI_ERR_ARG
    - Invalid pointer.
