problems with FORK() and WAITPID()

Dear All, I'm trying to write multithreading TCP Daemon which executes external program when new network connection arrives on a socket. After accept() I'm doing fork() for initiating of new child process, in which will be executed external program. After child creation I'm doing fork() again,...

waiting for multiple childs - C - waitpid

Hi gurus, I would like to fork more children and then write their return values: so far I tried: #include <stdio.h> #include <stdlib.h> #include <errno.h> #include <unistd.h> #include <sys/types.h> #include <sys/wait.h> int main(void) { pid_t pid; int rv=0, i; ...

[C]Fork and waitpid

Hi folks, I am writing a simple program to understand how fork() and waitpid works, but it doesn't seem that is working like I wanted. if(fork()==0){ //el hijo pid1=getpid(); printf("\nSoy el hijo %d",pid1); }else { //el padre if (fork()==0) { //el hijo pid2=getpid();...

gtk2::object

Gtk2::Object(3) 					User Contributed Perl Documentation					   Gtk2::Object(3)

NAME

       Gtk2::Object

HIERARCHY

	 Glib::Object
	 +----Glib::InitiallyUnowned
	      +----Gtk2::Object

METHODS

   object = Gtk2::Object->new ($object_class, ...)
       o   $object_class (string) package name of object to create

       o   ... (list) of property-name => value pairs

       Create a new object of type $object_class, with some optional initial property values.  You may see this used in some code as
       Gtk2::Widget->new, e.g.

	$window = Gtk2::Widget->new ('Gtk2::Window',
				     title => 'something cool',
				     allow_grow => TRUE);

       This is really just a convenience function that wraps Glib::Object->new.

   boolean = $object->bindings_activate ($keyval, $modifiers)
       o   $keyval (integer)

       o   $modifiers (Gtk2::Gdk::ModifierType)

       Although "activate" and "activate_event" are "Gtk2::Object" methods, as of Gtk 2.12 they will only actually invoke signals on a
       "Gtk2::Widget".	On a "Gtk2::Object" the return is always false (no binding activated).

   boolean = $object->bindings_activate_event ($event)
       o   $event (Gtk2::Gdk::Event)

   $object->destroy
       This is an explicit destroy --- NOT the auto destroy; Gtk2::Object inherits that from Glib::Object!

PROPERTIES

       'user-data' (gpointer : readable / writable / private)
	   Anonymous User Data Pointer

SIGNALS

       destroy (Gtk2::Object)
