Load all the data from an SDL data stream.


void* SDL_LoadFile_RW(SDL_RWops *src,
                      size_t *datasize,
                      int freesrc);

Function Parameters

src the SDL_RWops to read all available data from
datasize if not NULL, will store the number of bytes read
freesrc if non-zero, calls SDL_RWclose() on src before returning

Return Value

Returns the data, or NULL if there was an error.


The data is allocated with a zero byte at the end (null terminated) for convenience. This extra byte is not included in the value reported via datasize.

The data should be freed with SDL_free().


This function is available since SDL 2.0.6.
