Hi all,
1) I have a small doubt in Linux Basics.
Wether the Linux having threading concept ?
That depends on what you mean by a "thread". I suppose to most people the main difference between threads and processes are that threads share things like memory pages and file handles. In Linux processes _can_ share memory pages and file handles. _Posix_ threads share time slices, so that a multi-threaded process is not granted more CPU time than a non-threaded process
I heard Linux treat everything as a process ? Is it true ?
No. That was true for he Linux Kernel up to v 2.4. Threads were done as processes sharing resources. The (Posix) Library made them look similar to (Posix-) threads.
With v 2.6 we have "NPTL" ("Native Posix Thread Library"). Here a process can get multiple threads with support of the Kernel. The (Posix) Library makes them real (Posix-) threads.
If not how can i found that linux suppport threading concept ?
"Posix thread library".
2) I would like to know the difference between Process/Thread and
Task.
see above
