fork()

[munna_dude]

hi all
can fork is used as a thread?

tnak you in advance

[bhaslinux]

yes.
But fork creates processes. So the entire process will be duplicated and not just another instance of the thread !

how do i make a process sleep for n seconds?

i'm having a problem, when i create a process like

 
child2 = fork();
printf("%d", child2);

child2 gets printed twice. once as a 0 and once as its real process id. how can i make it print only once?

Hi,
Printf() is called once by ur parent process then by child process.so u get tw o ouptuts.
child process pid is always zero and parent process greater than zero.
use sleep() or wait() to delay process.

i found this link simple and easy

yeah..
i used pthreads concept

pthread_t thread1;
int iret1;
iret1=pthread_create( &thread1, NULL, myfunction, NULL);
//pthread_join( thread1, 0);

here my function having gtk application(gui)
in this it calls the browser, when the browser calls using threads my gui application getting
hanged, for that i used
pthread_join( thread1, 0);

still it is hanging..

i used this thread in othen function(not in main()).

can any help?

thank you in advance
