Name

SDL_IOFromDynamicMem — Use this function to create an SDL_IOStream
that is backed by dynamically allocated memory.

Header File

Defined in SDL3/SDL_iostream.h

Synopsis

#include "SDL3/SDL.h"

SDL_IOStream * SDL_IOFromDynamicMem(void);

Description

This supports the following properties to provide access to the memory and control over allocations:

· SDL_PROP_IOSTREAM_DYNAMIC_MEMORY_POINTER :
 a pointer to the internal memory of the stream. This can be set to NULL
 to transfer ownership of the memory to the application, which should free
 the memory with SDL_free (). If this is done, the next
 operation on the stream must be SDL_CloseIO ().

· SDL_PROP_IOSTREAM_DYNAMIC_CHUNKSIZE_NUMBER :
 memory will be allocated in multiples of this size, defaulting to 1024.

Return Value

( SDL_IOStream
*) Returns a pointer to a new

SDL_IOStream
structure or NULL on failure; call

SDL_GetError () for more information.

Thread Safety

It is safe to call this function from any thread.

Availability

This function is available since SDL 3.2.0.
