Is it ok that the following code: #include <alsa/asoundlib.h> int main(void) { void **hints; if (snd_device_name_hint(-1, "pcm", &hints) < 0) { return -1; } if (snd_device_name_free_hint(hints) < 0) { return -1; } if (snd_config_update_free_global() < 0) { return -1; } printf("Ok"); return 0; } exits with 0 and makes Valgrind return "still reachable: 65,368 bytes

I have some code here which is supposedly sending bytes of data to an iPhone using libusb, here’s the offending snippet: libusb_control_transfer(handle, 0x21, 1, 0, 0, buf, 0x800, 1000); This works fine but my question here is regarding the second parameter bmRequestType = 0x21, which according to the documentation represents the "request type field for
