a function's loaded address in memory

[sean yang]

I use ptrace() to get the PC of system call site.
Say I get two system call invocation during runtime, 
PC=0x8048988/sys_write() and PC=0x19279a/sys_write(). Can I know within 
which function the system call is invoked?

For example, the 0x8048988/sys_write() should be from the "int 80(I wrote in 
assembly)"
in main(); the 0x19279a/sys_write() should be from the "int 80" in the 
write() of libc.so.

If I can know write() is (dynamically) loaded to 0x192780--0x19279c, then I 
know that
0x19279a/sys_write() is from it because 0x19279a belongs to [0x192780, 
0x19279c].
My question is: is there an easy mechanism that I can get the information of 
which function is loaded where in a run?

Thanks a lot
