-2.6 Closure Example
-===================
-
-A trivial example that creates a new `puts' by binding `fputs' with
-`stdin'.
-
- #include <stdio.h>
- #include <ffi.h>
-
- /* Acts like puts with the file given at time of enclosure. */
- void puts_binding(ffi_cif *cif, unsigned int *ret, void* args[],
- FILE *stream)
- {
- *ret = fputs(*(char **)args[0], stream);
- }
-
- int main()
- {
- ffi_cif cif;
- ffi_type *args[1];
- ffi_closure *closure;
-
- int (*bound_puts)(char *);
- int rc;
-
- /* Allocate closure and bound_puts */
- closure = ffi_closure_alloc(sizeof(ffi_closure), &bound_puts);
-
- if (closure)
- {
- /* Initialize the argument info vectors */
- args[0] = &ffi_type_pointer;
-
- /* Initialize the cif */
- if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1,
- &ffi_type_uint, args) == FFI_OK)
- {
- /* Initialize the closure, setting stream to stdout */
- if (ffi_prep_closure_loc(closure, &cif, puts_binding,
- stdout, bound_puts) == FFI_OK)
- {
- rc = bound_puts("Hello World!");
- /* rc now holds the result of the call to fputs */
- }
- }
- }
-
- /* Deallocate both closure, and bound_puts */
- ffi_closure_free(closure);
-
- return 0;
- }
