Use this function to read 32 bits of big-endian data from an SDL_IOStream and return in native format.

Header File

Defined in <SDL3/SDL_iostream.h>


SDL_bool SDL_ReadU32BE(SDL_IOStream *src, Uint32 *value);

Function Parameters

SDL_IOStream * src the stream from which to read data.
Uint32 * value a pointer filled in with the data read.

Return Value

(SDL_bool) Returns SDL_TRUE on successful write, SDL_FALSE on failure; call SDL_GetError() for more information.


SDL byteswaps the data only if necessary, so the data returned will be in the native byte order.


This function is available since SDL 3.0.0.
