Hi, Yes, from our programs we call fork() which is a system call and all system call implementation will have the format of : sys_<system_call_name> So, do_fork() is the actual fork implementation whereas you can think of sys_fork() as a wrapper program. You can implement your own system call very easily. Just search for "adding a system call" in google and you will come across a lot of articles. hope this helps Karthik --- shinny@j02.itscom.net wrote: > Hi, all > > This question may be really basic though, > I'm studying how the linux creates a process and > schedules it on 2.6 at the moment. > The core function to create a process seems to be > do_fork() in kernel/fork.c. > And do_fork() is called from sys_fork() or > sys_clone(). > But we usually use fork() not sys_fork(), don't we? > So I downloaded the latest libc(glibc-2.3.2) source > and looked for fork(). > However there are several functions and files that > are likely to be fork(). > Which fork() in which file is the real we call from > our program? > > Regards, > Shinpei Kato > -- > Kernelnewbies: Help each other learn about the Linux > kernel. > Archive: > http://mail.nl.linux.org/kernelnewbies/ > FAQ: http://kernelnewbies.org/faq/ > __________________________________ Do you Yahoo!?
