Hello VxWorks literati We're considering moving to Linux and one of the questions that was asked is: How do you emulate what's best of the VxWorks shell? In VxWorks, the shell interpreter can call any library function currently loaded and execute it on the spot. For example, one can type at the shell: printf("Val = %d\n",x) and the library function printf will be executed and the current value of x will be searched in the symbol table and passed on to the printf function. Although this is a trivial example, perhaps the intended use would be more appropriate. Suppose a function called "foo(int a, double b)" exists in a shared library used by a currently executing process. Is there an "easy" way to ask the process to search its symbol table and execute foo(a,b) for us? Perhaps there's no easy way and each process now needs some form of IPC glued to it so we can funnel a command into it. Is there a Linux command to get the function pointer from a symbol table search? Am I making any sense? TIA & cheers
