CeCloseCallerBuffer (Windows Embedded CE 6.0)
1/6/2010
This function frees any resources that were allocated by CeOpenCallerBuffer. It performs any required write-back to the caller buffer due to out descriptors ARG_IO* or ARG_O*.
Syntax
HRESULT CeCloseCallerBuffer(
PVOID pDestMarshalled,
PVOID pSrcUnmarshalled,
DWORD cbSrc,
DWORD ArgumentDescriptor
);
Parameters
- pDestMarshalled
[in] Pointer to the buffer that was allocated by CeOpenCallerBuffer.
- pSrcUnmarshalled
[in] Source pointer that was passed to CeOpenCallerBuffer.
- cbSrc
[in] Buffer size that was passed to CeOpenCallerBuffer.
- ArgumentDescriptor
[in] Descriptor that was passed to CeOpenCallerBuffer.
Return Value
- E_ACCESSDENIED
Required write-back could not be performed. If this error occurs, resources are still released and the marshaled pointer is no longer accessible.
- E_INVALIDARG
The pSrcUnmarshalled parameter was NULL, the length was zero, or some other parameter was invalid.
- S_OK
