@sorted = sort @list; @sorted = sort { $a cmp $b } @list; sub compare { $a cmp $b } @sorted = sort compare @list; The three examples above do exactly the same thing. If you don't supply any comparator function or block, sort assumes you want the list on its right sorted lexically. This is ...

Let's say we want to use libc's ntohl function. First, we must load libc.so: >>> from ctypes import * >>> libc = cdll.LoadLibrary('libc.so.6') >>> libc <CDLL 'libc.so.6', handle baadf00d at 0xdeadbeef> Then, we get the function object: >>> ntohl = l...

The most basic object is an int: >>> obj = ctypes.c_int(12) >>> obj c_long(12) Now, obj refers to a chunk of memory containing the value 12. That value can be accessed directly, and even modified: >>> obj.value 12 >>> obj.value = 13 >>> obj c_...
