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.

NAME
MPI_Status_f2c - Convert a status from its Fortran representation to its C representation SYNOPSIS
#include <mpi.h> int MPI_Status_f2c(MPI_Fint *f_status, MPI_Status *c_status) INPUT PARAMETER
f_status - Fortran status OUTPUT PARAMETER
c_status - C status NOTES FOR FORTRAN
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list. ierr is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked with the call statement. All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran. ERRORS
If an error occurs in an MPI function, the current MPI error handler is called to handle it. By default, this error handler aborts the MPI job. The error handler may be changed with MPI_Errhandler_set ; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned (in C and Fortran; this error handler is less useful in with the C++ MPI bindings. The predefined error handler MPI::ERRORS_THROW_EXCEPTIONS should be used in C++ if the error value needs to be recovered). Note that MPI does not guarantee that an MPI program can continue past an error. All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of the function and Fortran routines in the last argument. The C++ bindings for MPI do not return error values; instead, error values are communicated by throwing exceptions of type MPI::Exception (but not by default). Exceptions are only thrown if the error value is not MPI::SUCCESS . Note that if the MPI::ERRORS_RETURN handler is set in C++, while MPI functions will return upon an error, there will be no way to recover what the actual error value was. MPI_SUCCESS - No error; MPI routine completed successfully. SEE ALSO
