sdl_init.nim

Header file for initialization and shutdown functions.

Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.

SDL officially supports Windows, Mac OS X, Linux, iOS, and Android. Support for other platforms may be found in the source code.

SDL is written in C, works natively with C++, and there are bindings available for several other languages, including C# and Python.

This library is distributed under the zlib license, which can be found in the file "SDL-COPYING.txt".

The best way to learn how to use SDL is to check out the header files in the "include" subdirectory and the programs in the "test" subdirectory. The header files and test programs are well commented and always up to date. More documentation and FAQs are available online at: http://wiki.libsdl.org

proc init*(flags: uint32): cint {.cdecl, importc: "SDL_Init", dynlib: SDL2_LIB.}

This function initializes the subsystems specified by flags Unless the INIT_NOPARACHUTE flag is set, it will install cleanup signal handlers for some commonly ignored fatal signals (like SIGSEGV).

Return 0 on success or a negative error code on failure.

proc initSubSystem*(flags: uint32): cint {.cdecl, importc: "SDL_InitSubSystem", dynlib: SDL2_LIB.}

This function initializes specific SDL subsystems.

Subsystem initialization is ref-counted, you must call sdl.quitSubSystem() for each sdl.initSubSystem() to correctly shutdown a subsystem manually (or call sdl.quit() to force shutdown).

If a subsystem is already loaded then this call will increase the ref-count and return.

proc quitSubSystem*(flags: uint32) {.cdecl, importc: "SDL_QuitSubSystem", dynlib: SDL2_LIB.}

This function cleans up specific SDL subsystems.

proc wasInit*(flags: uint32): uint32 {.cdecl, importc: "SDL_WasInit", dynlib: SDL2_LIB.}

This function returns a mask of the specified subsystems which have previously been initialized.

If flags is 0, it returns a mask of all initialized subsystems.

proc quit*() {.cdecl, importc: "SDL_Quit", dynlib: SDL2_LIB.}

This function cleans up all initialized subsystems. You should call it upon all exit conditions.
