Function Documentation

void cleanup (  int  status, const char *  fmt,   ... )

Free resources and exit. Is called, whenever an error occurs or the program terminates noramlly. Parameters: status  The exit-code. fmt  Additional output-message (used e.g. for describing the error that caused the cleanup in more detail).

void getinput (  void   )

Input-handler. Polls the input-devices. Keyboard, Mouse and Window-manager-events are handled here.

void gtk_gui_iteration (  void   )

One gtk_main()-iteration. Instead of calling gtk_main() (which does not return control to the program until termination) each iteration is executed explicitly through this function-call.

int initapp (  int  argc, char **  argv )

The application's "heart". int main(int argc, char **argv) - "abstraction" This makes it possible to make a "real" Win32 application out of this (so no console-window is opened upon double-click in the explorer! Don't forget to remove /DCONSOLE when compiling the program). Look at w32main.c for details! Parameters: argc  The ANSI-C argument-count. argv  The ANSI-C argument-vector. Returns: Exit code (actually never reached...cleanup() handles all the exits).

void initSDL (  int  xs, int  ys, int  bpp, int  fullscreen )

Create SDL-window. Allocates the necessary buffers for rendering. Parameters: xs  The SDL-window's width. ys  The SDL-window's height. bpp  The SDL-window's bit-depth. fullscreen  Flag that indicates, if the SDL-window is fullscreen or windowed.

void resizeSDLscreen (  int  new_w, int  new_h )

Resize screen. Is called, whenever the window-size changes. Reallocates the necessary buffers for rendering. Parameters: new_w  The new width. new_h  The new height.
