Calling the original function after tweaking arguments is an incorrect use of the R-API?

I am trying to make the R_ReadConsole API call. However, since a different

Controlling stdin and stdout in an embedded R instance
...ividually send
native R commands to an embedded console and then consume the output of
these commands. Specifically, I cannot send a set of commands to the
embedded console and then consume all of the output after the execution
completes. I have unsuccessfully attempted to assign values to the
ptr_R_ReadConsole and ptr_R_WriteConsole function pointers defined in
Rinterface.h but do not know if this is a valid approach. I am working
in Ubuntu 10.04 and thus the Windows example at the following address is
not applicable.

Calling R from C - part way there but need a push!
...code from a file of my own",
"set value of x", "make a call and read the values back into my C
program"?
Help is much appreciated.
Regards, Max
(1) The most likely include file is Rinterface.h and within that the
most likely candidates seem to be:
extern int (*ptr_R_ReadConsole)(const char *, unsigned char *, int,
int);
extern void (*ptr_R_WriteConsole)(const char *, int);
extern void (*ptr_R_WriteConsoleEx)(const char *, int, int);
but it turns out that they assume that R is running the terminal and
these are requests to R to display or read from R's console....
