暂停和恢复 Qt 中由 QProcess 启动的子进程

Question

How can I suspend and resume a subprocess that I started as a QProcess in Qt? Is there a Qt function for that, or if not, a platform-specific one that would work on Linux?

Answer 1

Since I'm on linux, I used the kill() function.

#include <signal.h>
...
kill(process->pid(), SIGSTOP); // suspend
kill(process->pid(), SIGCONT); // resume
