exit(), _exit() and sys_exit()

[Rajaram Suryanarayanan <rajaram_linux@xxxxxxxxx>]

Hi,

 

What is the difference between exit and _exit() ?

I studied in some google links that exit() is a C library wrapper and _exit() is the system call. Then what is sys_exit() ? The system calls should begin with "sys_" as per convention. Am I right ?

 

Thanks,

Rajaram.
