Go 슬라이스 포인터를 C 함수에 전달하는 방법은 무엇입니까?

// C function signature: int f(int *count, char ***strs)
import "C"

func go_f(strs []string) int {
    count := len(strs)
    c_count := C.int(count)

    // Allocate an array in C memory to store the strings
    cArray := C.malloc(C.size_t(c_count) * C.size_t(unsafe.Sizeof(uintptr(0))))

    // Convert the C array to a Go array so we can access its elements
    a := (*[1<<30 - 1]*C.char)(cArray)

    // Copy the Go strings into the C array
    for index, value := range strs {
        a[index] = C.CString(value)
    }

    // Call the C function with a pointer to the C array
    err := C.f(&c_count, (***C.char)(unsafe.Pointer(&cArray)))

    // Free the C array
    C.free(cArray)

    return int(err)
}
