@Jeffersonquesado Windows 7. I know that in Linux the code is very short. But in Windows, by the tutorials I could not. So I thought I’d create one myself, but I wanted to know which libraries to use.

Maybe I’m taking a risk, but I voted to reopen giving Lacobus the opportunity to answer (I’m not going to say it works, because it’s not something I dominate). ps: @lacobus I don’t dominate C as much as you do, but I believe that

stdbool.hwas introduced in the C99 if I’m not mistaken.– Guilherme Nascimento
Try the following ----- #include <windows. h> #include <iostream> using namespace Std; typedef MCIERROR WINAPI (CDROM)(const char,char*,unsigned,HWND); CDROM pcd; void Abrir cd(){ pcd("Set Cdaudio Door Open",NULL,0,NULL); } void Fecha cd(){ pcd("Set Cdaudio Door Closed",NULL,0,NULL); }
