mpi_info_f2c

MPI_Info_f2c(3) 						      LAM/MPI							   MPI_Info_f2c(3)

NAME

       MPI_Info_f2c -  Convert a info handle from its Fortran representation to its C representation

SYNOPSIS

       #include <mpi.h>
       MPI_Info
       MPI_Info_f2c(MPI_Fint f_handle)

INPUT PARAMETER

       f_handle
	      - Fortran info handle

RETURN VALUE

       info   - C info handle

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

       This function does not return the normal MPI_SUCCESS integer value upon success.  Instead, it returns a handle to the converted object.	If
       an error occurs, the appropriate NULL handle will be returned.

SEE ALSO

       MPI_Info_c2f(3)

MORE INFORMATION

       For more information, please see the official MPI Forum web site, which contains the text of both the MPI-1  and  MPI-2	standards.   These
       documents contain detailed information about each MPI function (most of which is not duplicated in these man pages).
