# xcurl\_global\_init\_mem

Initializes XCurl with custom memory allocators.

<a id="syntaxSection" />

## Syntax

```cpp theme={null}
CURL_EXTERN CURLcode xcurl_global_init_mem(long flags,
    xcurl_alloc_memory_callback m,
    xcurl_free_memory_callback f,
    xcurl_realloc_memory_callback r,
    curl_strdup_callback s,
    xcurl_calloc_memory_callback c
)
```

<a id="parametersSection" />

### Parameters

*flags*   \_In\_\
Type: long

This parameter is ignored by XCurl.

*m*   \_In\_\
Type: xcurl\_alloc\_memory\_callback\*

malloc() replacement

*f*   \_In\_\
Type: xcurl\_free\_memory\_callback\*

free() replacement

*r*   \_In\_\
Type: xcurl\_realloc\_memory\_callback\*

realloc() replacement

*s*   \_In\_\
Type: curl\_strdup\_callback\*

strdup() replacement

*c*   \_In\_\
Type: xcurl\_calloc\_memory\_callback\*

calloc() replacement

### Return value

If this function returns a non-zero value, then something went wrong and you cannot use the other curl functions.

<a id="remarksSection" />

## Remarks

This function is identical to [curl\_global\_init\_mem](https://curl.haxx.se/libcurl/c/curl_global_init_mem.html), except that this version initializes XCurl with custom memory allocators.

XCurl relies on the Gaming Runtime, and therefore cannot be initialized until after you run [XGameRuntimeInitialize](/reference/system/xgameruntimeinit/functions/xgameruntimeuninitialize).

Wherever you would have included `curl.h` in your game code, you must replace it with `xcurl.h`.

## Requirements

**Header:** XCurl.h

**Library:** xcurl.lib

**Supported platforms:** Windows, XBOX One family consoles and XBOX Series consoles
