# HCGetHttpCallPerformFunction

Returns the current HCCallPerformFunction callback which implements the HTTP perform function on the current platform.

## Syntax

```cpp theme={null}
HRESULT HCGetHttpCallPerformFunction(  
         HCCallPerformFunction* performFunc,  
         void** performContext  
)  
```

### Parameters

*performFunc*   \_Out\_\
Type: HCCallPerformFunction\*

Set to the current HTTP perform function. Returns the default routine if not previously set.

*performContext*   \_Out\_\
Type: void\*\*

The context for the callback.

### Return value

Type: HRESULT

Result code for this API operation. Possible values are S\_OK, E\_HC\_ALREADY\_INITIALISED, or E\_INVALIDARG.

## Remarks

This can be used along with HCSetHttpCallPerformFunction() to build a filter that monitors and modifies all HTTP calls, while still using the default HTTP implementation.

## Requirements

**Header:** httpProvider.h

**Library:** libHttpClient.GDK.lib
