        Calling Sequence

        #include <dglib.h>
         int *getfp(), *curfp;
        curfp = getfp();

        (or)

        $builtin int *getfp();
        short int *curfp;
        curfp = getfp();


        Description

        The getfp function returns the frame pointer of the environment
        of the parent process.  The first version of the calling sequence
        noted above uses a function call.  The second might generate
        smaller or faster code, but may not run under other C compilers.


        Returns

        The getfp function returns a frame pointer.

        Example

        /* Program test for the getfp() function */

        #include <dglib.h>

        int  *getfp(), *curfp;

        main() {
            printf("My frame pointer = %o.\n", curfp = getfp());
        }

        A call to the program test generates the output

        My frame pointer = 16000012650.

        Note that the frame pointer will vary.
