#ifndef PLATFORM_TYPES_H
#define PLATFORM_TYPES_H

/* Platform-dependent types are defined here.
  These types must be defined by any platform:
  Fl_Offscreen, Fl_Bitmask, Fl_Region, FL_SOCKET, GLContext, struct dirent, struct stat,
  fl_intptr_t, fl_uintptr_t

  NOTE: *FIXME* AlbrechtS 13 Apr 2016 (concerning FL_SOCKET)
  ----------------------------------------------------------
    The Fl::add_fd() API is partially inconsistent because some of the methods
    explicitly use 'int', but the callback typedefs use FL_SOCKET. With the
    definition of FL_SOCKET below we can have different data sizes and
    different signedness of socket numbers on *some* platforms.
