SDL_RWclose
Use this function to close and free an allocated SDL_RWops structure.
Contents
Syntax
int SDL_RWclose(struct SDL_RWops* context)
Function Parameters
context |
SDL_RWops structure to close |
Return Value
Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
Code Examples
Uint8 buf[256];
SDL_RWops *rw = SDL_RWFromFile("test.bin", "r");
if (rw != NULL) {
SDL_RWread(rw, buf, sizeof (buf), 1);
SDL_RWclose(rw);
}
// Go on and use the data in buf...
Remarks
SDL_RWclose() closes and cleans up the SDL_RWops stream. It releases any resources used by the stream and frees the SDL_RWops itself with SDL_FreeRW(). This returns 0 on success, or -1 if the stream failed to flush to its output (e.g. to disk).
Note that if this fails to flush the stream to disk, this function reports an error, but the SDL_RWops is still invalid once this function returns.
SDL_RWclose() is actually a macro that calls the SDL_RWops's close method appropriately, to simplify application development.
