Typedefs
typedef std::shared_ptr< Attachable >	AttachableRef
typedef uintptr_t	handle_t
	A native handle type, big enough to store a pointer.
using	StringAttachables = StringHashMapWrap<AttachableRef, std::nullptr_t, nullptr>
template<typename K, typename V>
using	StringlikeHashMap = std::unordered_map<K, V, jau::string_hash, std::equal_to<>>

Functions
std::string	asset_dir () noexcept
template<typename T, typename U>
U	castOrThrow (T has)
template<typename T, typename U>
bool	checkOverflow (T has)
int	expected_fps () noexcept
	Returns expected fps, either gpu_forced_fps() if set, otherwise monitor_fps().
jau::fraction_timespec	expected_framedur () noexcept
	Returns the expected frame duration in [s], i.e.
jau::fraction_timespec	getElapsedMonotonicTime () noexcept
	Returns the elapsed monotonic time since init_gfx_subsystem, synchronized with the gfx subsystem timer.
float	gpu_avg_fps () noexcept
	Returns the measured gpu fps each 5s, starting with monitor_fps()
const jau::fraction_timespec &	gpu_avg_framedur () noexcept
	Returns the measured gpu frame duration in [s] each 5s, starting with 1/gpu_avg_fps()
int	gpu_forced_fps () noexcept
	Returns optional forced frames per seconds or -1 if unset, set via set_gpu_forced_fps().
size_t	handle_events () noexcept
	GFX Toolkit: Handle windowing and keyboard events.
bool	init_gfx_subsystem (const char *exe_path)
	GFX Toolkit: Initialize the subsystem once.
bool	is_gfx_subsystem_initialized () noexcept
std::string	lookup_and_register_asset_dir (const char *exe_path, const char *asset_file="fonts/freefont/FreeSansBold.ttf", const char *asset_install_subdir="gamp") noexcept
bool	mainloop_default () noexcept
	Performs the whole tasks for all created gamp::wt::Window instances.
void	mainloop_void () noexcept
	Calls mainloop_default(), but exits application if returning false.
int	monitor_fps () noexcept
	Monitor frames per seconds.
std::string	resolve_asset (const std::string &asset_file, bool lookup_direct=false) noexcept
void	set_gpu_forced_fps (int fps) noexcept
	Optional forced frames per seconds, pass to swap_gpu_buffer() by default.
void	shutdown () noexcept
void	swap_gpu_buffer (int fps) noexcept
	GFX Toolkit: Swap GPU back to front framebuffer of all windows using given fps, maintaining vertical monitor synchronization if possible.

Detailed Description

Gamp: Graphics, Audio, Multimedia and Processing Framework (Native C++, WebAssembly, ...)

Gamp addresses native hardware accelerated graphics, audio, multimedia and processing. It is implemented in C++, supports WebAssembly and perhaps interfacing w/ other languages/systems.
