It depends on the OS that you are using.  On Linux x86_64, long is 64
bits.  On Windows, long is 32 bits.

The C99 types such as uint32_t, int64_t, etc. are the way to go if bits
matter.  If you need an int that can hold a pointer, use intptr_t.

Most C/C++ compilers lower than C99 have these types as well, but under
slightly different names.
