Documentation

lithon_SDL_Swap16 Source #

Arguments

:: Uint16	`x` the value to byte-swap.
-> IO Uint16

Byte-swap an unsigned 16-bit number.

The SDL_Swap16 macro as a function. It always byte-swaps the value, whatever the system's byte order; SDL_Swap16LE or SDL_Swap16BE are what you want in most cases.

Returns: x, with its bytes in the opposite endian order.
Thread safety: It is safe to call this function from any thread.
C declaration: lithon_SDL_Swap16, defined at sdl3-bindgen-sys/SDL_endian_shims.h 38:26

Since: 3.2.0

lithon_SDL_Swap32 Source #

Arguments

:: Uint32	`x` the value to byte-swap.
-> IO Uint32

Byte-swap an unsigned 32-bit number.

The SDL_Swap32 macro as a function. It always byte-swaps the value, whatever the system's byte order; SDL_Swap32LE or SDL_Swap32BE are what you want in most cases.

Returns: x, with its bytes in the opposite endian order.
Thread safety: It is safe to call this function from any thread.
C declaration: lithon_SDL_Swap32, defined at sdl3-bindgen-sys/SDL_endian_shims.h 57:26

lithon_SDL_Swap64 Source #

Arguments

:: Uint64	`x` the value to byte-swap.
-> IO Uint64

Byte-swap an unsigned 64-bit number.

The SDL_Swap64 macro as a function. It always byte-swaps the value, whatever the system's byte order; SDL_Swap64LE or SDL_Swap64BE are what you want in most cases.

Returns: x, with its bytes in the opposite endian order.
Thread safety: It is safe to call this function from any thread.

lithon_SDL_Swap16LE Source #

Arguments

:: Uint16	`x` the value to swap, in littleendian byte order.
-> IO Uint16
