This function gets the packet size of the next packet to read.

Syntax

HRESULT WapGetNextPrimitiveSize(
  const WAP_HANDLE whHandle,
  DWORD* const pdwNextPrimitiveSize 
);

Parameters

• whHandle
  [in] The WAP handle returned by WapOpen.

• pdwNextPrimitiveSize
  [out] Pointer to the size, in bytes, of the buffer for the next packet to read, via a call to WapRead. All protocol data units (PDUs) are derived from the WAP_PRIMITIVE_BASE structure.

Return Value

Returns S_OK if successful. If unsuccessful, this function returns the standard values E_INVALIDARG, E_OUTOFMEMORY, E_UNEXPECTED, and E_FAIL.

Remarks

Subsequent calls to WapGetNextPrimitiveSize will retrieve the size of the next packet only after the current primitive has been read by the WapRead function.
