Load all the data from an SDL data stream.

Header File

Defined in SDL_rwops.h


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

Function Parameters

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

Return Value

(void *) 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.
