[Haskell-cafe] Wondering about c type in haskell.

Hi, There are times, when we need to make some system calls, or call C library. So we have to deal with C data types. For example, CPid, which is an integer, actually. So we can do "fromIntegral pid". Then why do not we define "type CPid = Integer", and convert Haskell Integer with C Int internally. So the "user" does not have to care about the type convert (everywhere, which is ugly). And, specially, when doing something like serialisation, for Haskell Integer, the user does not have to do things with precision. But for CPid, without the fromIntegral, we have to specify its precision, well, on different machine/OS, the precision may not be the same. -- 竹密岂妨流水过 山高哪阻野云飞
