This function reads a packet.

Syntax

HRESULT WapRead(
  const WAP_HANDLE whHandle,
  WAP_PRIMITIVE_BASE* const pwpbPrimitiveBuffer,
  const DWORD dwPrimitiveBufferSize 
);

Parameters

  • whHandle
    [in] The WAP handle retrieved by the WapOpen function.
  • pwpbPrimitiveBuffer
    [out] Pointer to a buffer that contains a layer-specific structure of type WAP_PRIMITIVE_BASE. All protocol data units (PDUs) are derived from the WAP_PRIMITIVE_BASE structure. If the buffer indicated by this parameter is too small to hold the primitive, the function will return E_FAIL.
  • dwPrimitiveBufferSize
    [in] The size, in bytes, of the buffer indicated by pwpbPrimitiveBuffer. This value can be obtained by calling WapGetNextPrimitiveSize.
