[赤石科技] 一键弹出U盘.exe

合集 · 赤石 (11)

Description

C++获取U盘太麻烦了干脆直接_popen调用wmic了,11行代码,编译即用
源码:
#include <windows.h>
#include <stdio.h>
int main() {
	char l[20],p[10]= "\\\\.\\";
  FILE* f = _popen("wmic LogicalDisk where \"DriveType='2'\" get DeviceID", "r");
	fgets(l, sizeof(l), f),fgets(l, sizeof(l), f),fclose(f),strncat(p, l, sizeof(p)-strlen(p)-1);
	HANDLE h = CreateFile(p, GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL);
	DWORD b;
	DeviceIoControl(h, IOCTL_STORAGE_EJECT_MEDIA, NULL, 0, NULL, 0, &b, NULL);
  CloseHandle(h);
}
