Help me about libMAD

  Hi,
        I just compled the libmad via Microsoft Visual C and added minimad.c to the workspace.
        But the workspace compiling does not pass because following files unistd.h,sys/stat.h and sys/mman.h which declared in minimad.c don't exsit.
   
  Error like this:
  =========================
  Deleting intermediate files and output files for project 'app - Win32 Debug'.
--------------------Configuration: app - Win32 Debug--------------------
Compiling...
minimad.c
e:\libmad-0.15.1b\minimad.c(23) : fatal error C1083: Cannot open include file: 'unistd.h': No such file or directory
Error executing cl.exe.
  app.exe - 1 error(s), 0 warning(s)
  =========================
   
        So could you tell me what should I do to make the compiling pass ?
        Also, I want to know how  to use the low-level API ?
   
  Best regards,
