I've been having problems with a software package for which I only have a binary with no debugging symbols. In talking to the folks that wrote the software I know what arguments the routine takes I just need to be able to see them in the debugger. Here's what I've done: Fire up the program. Attach to the pid of the running process with 'gdb lsv 10336'. I've set the breakpoint at the routine that I'm interested in 'break LH2P' and I've coerced the program to run to the breakpoint. Here's where I'm lost. I'm back in gdb and it is waiting for me to tell it what to do. I know the function LH2P takes one argument a 'char *'. How do I view a function's arguments? With debugging symbols this is as easy as 'where'. I figured 'info args' would be the ticket but all it says is 'No symbol table info avialable'. Now I'm betting the information from 'info frame' is the key but how to decipher it.
