[Haskell-cafe] Help Haskell driving Medical Instruments

[Philippos Apolinarius]

Hi, Jason.
I don't know how to mark the call unsafe. And I don't know what is a *Nix (perhaps unix?). I am running the main program on Windows.  Here is the compilation script:

ghc -fglasgow-exts serial.c  %1.hs -L./ -ljapi --make
erase *.hi
erase *.o
strip %1.exe

BTW I figure out that passing an argument to closecport only makes the problem occur less often. Here is an example:

D:\ghc\sensors>strip temper.exe
D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe
4

D:\ghc\sensors>temper.exe

D:\ghc\sensors>temper.exe

D:\ghc\sensors>temper.exe

D:\ghc\sensors>temper.exe

D:\ghc\sensors>temper.exe

  Does marking the call `unsafe` make any difference?

  This is running on a *NIX of some flavour?
