How do i find address?

How can I find the address (the return address is sufficient) of the caller of a function ?

• I'm trying to debug some code and I want to pull the return address of the stack. I'm running this on a MIPS core. I tried putting a local variable at the bottom of the local variable list, a ULONG, (I thought that would the last local variable just above the return address). I then took the address and added 1 to it (assuming that adding one to ULONG will add 4 to the address). However, I didn't get an address that mapped anywhere in the symbol table. If someone knows how I can get this. If you can give me an assembly snippet or whatever that'll be great.

  I'm not familiar with the MIPS architecture, but if you are using gcc, there is a gcc builtin for this purpose: void * __builtin_return_address (unsigned int level); The gcc builtin documentation (http://gcc.gnu.org/onlinedocs/gcc/Return-Address.html) says the following: This function returns the return address of the current function, or of one of its callers. The level argument is number of frames to scan up the call stack. A value of 0 yields the return address of the current function, a value of 1 yields the return address of the caller of the current function, and so forth So, you can do something like this: #include <stdio.h> void foo() { printf("%p\n", __builtin_return_address(1)); } int main (int argc, const char* argv[]) { foo(); }
