Windowsのsystem関数でLinuxの/dev/nullを実現する

Last updated at Posted at 2020-12-16

windowsのsysytem関数で、exeから他のexeを呼ぶ際に以下を実現したかったのでメモ

  • 呼びだすexeの標準出力を表示させない
  • 呼びだすexeの戻り値だけ利用したい
# include <iostream>
# include <process.h>

int main()
{
    int result;

    //「> nul」で標準出力を表示させません。
    result = system("Test.exe > nul"); 
    printf("-------------------------\n");
    printf("result : %d\n", result);
}
