// Demonstrate on-demand ptrace() of a single thread, not affecting any other | |
// thread in the process. The Linux/x86-64 version. | |
// | |
// This differs from ptrace() examples I could find on the Web by: | |
// * Tracing the parent process from the child (same as Crashpad) | |
// * Allowing to run threads in the background | |
// | |
// This is just a *demo*. A lot of error situations are not checked for, same | |
// for process states (wrt to signals, for example). Uses the mix of | |
// fork(2)+threads and malloc() in the forked process. Uses pipe() for message |
