Suspending system using c++ program.

Question

Hi All,

I am trying to suspend my system using a c++ program using SetSuspendState method but I am facing issue during linking.

I am using g++-4 (GCC) 4.3.4 20090804 (release) 1 compiler on Windows 7 OS (64bit).

The code I have written is

#include <iostream>
#include "windows.h"
#include "powrprof.h"

using namespace std;

int main() {

    cout << SetSuspendState(false, true, false);
    return 0;
}

Following is the error I am facing:

/cygdrive/c/Users/Vikas/AppData/Local/Temp/ccFpLgPi.o:suspend.cpp:(.text+0xa4): undefined reference to `_SetSuspendState@12' collect2: ld returned 1 exit status

Kindly help me in resolving this issue.

Thanks in advance ...

Answer 1

As msdn says you need to link PowrProf.lib.

Answer 2

I believe dlltool can be used to create import libraries from DLLs for use with GCC under Cygwin. The DLL exporting the functions pwrprof.dll should be located in your Windows system directory somewhere.
