Say, for example, I have a C source file with a method like foo(a) where a is a character.
I want to print the output of foo for every character is there an easier way than going through systematically and entering p foo('a') then p foo('b')?
Ideally I'd really like to script it so it's a bit quicker.
I managed to figure it out, my code was basically:
define foo_test
set $a = 97
set $b = 123
while $a < $b
p (char)foo($a)
set $a = $a + 1
end
end
perl -e 'foreach $i ("a" .. "z") { print "print foo('\''$i'\'')\n"; }' > /tmp/t.$$ &&
gdb --batch -x /tmp/t.$$ ./a.out ; rm -f /tmp/t.$$
You should also look into GDB Python scripting.
It sounds like the first thing you should add is some "Breakpoint command lists", those will let you run some gdb commands after a breakpoint has hit.
So if you add so your print runs when someone calls the functions foo, you should be are getting kind of close.
