Since Windows API (and MinGW) doesn’t have fork() \/ exec() calls, I love GLib’s g_spawn_sync() and its friends to spawn child process in portable (and Unix like) way.
\nHowever, GLib provides nothing like kill() to terminate processes. So I have to find a way to kill a process by myself. As a portable process identifier, g_spawn_sync() gives GPid. This is defined in GLIB_PREFIX\/lib\/glib-2.0\/include\/glibconfig.h as:
\n– Unix: typedef int GPid;
\n– Win32: typedef void * GPid;
\nThe one for Unix is equal to pid, and the one for Win32 is equal to HANDLE (defined in winnt.h, as “typedef void *HANDLE;”).
\nSo, a process launched by g_spawn_sync() may be killed by:
\nkill(GPid p, 15);
\nTerminateProcess(GPid p, UINT return_code);
\nMSDN document says “The state of global data maintained by dynamic-link libraries (DLLs) may be compromised if TerminateProcess is used rather than ExitProcess.”
\nSource code of a Gimp plugin<\/a> gives a good example, but I haven’t tested it yet. Hope this works…<\/p>\n","protected":false},"excerpt":{"rendered":"
