When you look up a Scheme function using scm_c_lookup, it doesn't return
the procedure. It returns the variable that contains the procedure. To then get the procedure, you have to dereference the variable using scm_variable_ref.

I would call the function this way...

int main (int argc, char *argv[])
   SCM func_symbol;
   SCM func;
scm_init_guile(); func_symbol = scm_c_lookup("write");
   func = scm_variable_ref(func_symbol);
scm_call_1 (func, scm_int2num(10));
