Programming

Hi,

I was trying to find from the function which is called by some other function but is it possiable by the calling funcation that who is calling me? For example

int function1()
{
// do something
return 0 ;
}

char function2()
{
// do something
function1() ; // is function2 knows function2 is calling me?
return '' ;
}

int main()
{
function1() ; // is function1 knows I called by main?
return 0 ;
}

by doing this we can able to track the program but this facility is there when we use debugger or when we debug our code but how to do that programatically I am not sure unix has stack tracing facility.

any help regarding this?

Thanks in advance
Balasubramanian.
