Hi! I'm trying to make a procedure that takes one argument (another procedure) and converts it to a C function, assigning it to a function pointer in C. Then I want to call that function from that pointer in C. I'm aware that the typical way to do this is with c-declare in a static way, but I need to be able to achieve the same without using c-declare. My current attempt: (define (uno) 1) (define bind (c-lambda (scheme-object) void "simple_callable = ___CAST(void (*)(),___arg1);")) (bind uno) ...then the C part, same file: // before void (*simple_callable)(void); // after (bind uno) is executed (*simple_callable)(); I guess that I'm doing either the input type or the cast (or both) wrong. Probably I'm assuming to much simply casting a "scheme-object" to a void(*)(). Is this what I'm trying to do even possible? Thanks a lot! Álvaro
