# SDL\_GetOriginalMemoryFunctions(3)

Get the original set of SDL memory functions.

## NAME

SDL\_GetOriginalMemoryFunctions - Get the original set of SDL memory functions.

## HEADER FILE

Defined in SDL3/SDL\_stdinc.h

## SYNOPSIS

```
#include "SDL3/SDL.h"
```

**void SDL\_GetOriginalMemoryFunctions(SDL\_malloc\_func \*malloc\_func,**                                 **SDL\_calloc\_func \*calloc\_func,**                                 **SDL\_realloc\_func \*realloc\_func,**                                 **SDL\_free\_func \*free\_func);**

## DESCRIPTION

This is what  **SDL\_malloc**\
  and friends will use by default, if there has been no call to  **SDL\_SetMemoryFunctions** . This is not necessarily using the C runtime's **malloc** functions behind the scenes! Different platforms and build configurations might do any number of unexpected things.

## FUNCTION PARAMETERS

- *malloc\_func*

  filled with malloc function.

- *calloc\_func*

  filled with calloc function.

- *realloc\_func*

  filled with realloc function.

- *free\_func*

  filled with free function.

## THREAD SAFETY

It is safe to call this function from any thread.

## AVAILABILITY

This function is available since SDL 3.2.0.
