Subject: Is it possible to get the return address in a system call function?
Date: Tue, 2 Aug 2005 02:57:47 -0400	[thread overview]
Message-ID: <4ae3c14050801235711055125@mail.gmail.com> (raw)

Let me clarify with an example: 

test.c:

******
open("abc.txt", O_RDONLY);
i ++;

Apparently, after the system call  "open" in the kernel, the system
will return to the instruction "i++".  My question is: can we find out
the instruction pointer in  sys_open? If so, how?

Thanks!

xin
