C bindings.

[Prasanna Kumar]

Hi All,

I am also interested in knowing the answer to the
questions asked by Sachin.

i. How does one get the address of C functions, which
I can use while calling "C" functions in my forth
code?

Thanks in advance.

Hi all,

I want to call c functions from my forth code.

In the mailing list i found following>

Please tell me how can I get the address of the c
function??

Please let me know if there are other issues involved
in this as I am very little aware of the whole system
trying to get familiar with the things.

Thanks in Advance

Sachin

During C initialization you can do

bind_func("forth-word-name", c_function_name );

then you can call void c_function_name(void) by calling forth-word-name
in forth. See arch/x86/boot.c and arch/x86/openbios.c
