I've noticed that functions like strlen and strcmp are
available for use in expressions like
(gdb) print strcmp(s, "foo!")
during my debugging sessions with GDB.
Is the entire C library available for expressions?
Thanks!

I've just answered this one, so I have it handy...

They aren't "allowed" per se. You're calling functions in the program
you're debugging when you do this.
So, in short, whatever functions are linked in to the program you're
debugging are available.
