C++ (Cpp) func_cb Examples

Example #1

File: u_fastboot.c Project: kishoreinme/uboot

void rx_handler_command(struct usb_ep *ep, struct usb_request *req)
{
	char response[RESPONSE_LEN];
	char *cmdbuf = req->buf;
	void (*func_cb)(struct usb_ep *ep, struct usb_request *req) = NULL;
	int i;

	sprintf(response, "FAIL");
	for (i = 0; i < ARRAY_SIZE(cmd_dispatch_info); i++) {
		if (!strcmp_l1(cmd_dispatch_info[i].cmd, cmdbuf)) {
			func_cb = cmd_dispatch_info[i].cb;
			break;
		}
	}

	if (!func_cb)
		fastboot_tx_write_str("FAILunknown command");
	else

	if (req->status == 0) {
        *cmdbuf = '\0';
		req->actual = 0;
