PackDDElParam function

Packs a Dynamic Data Exchange (DDE) lParam value into an internal structure used for sharing DDE data between processes.

Syntax


LPARAM WINAPI PackDDElParam(
  _In_  UINT msg,
  _In_  UINT_PTR uiLo,
  _In_  UINT_PTR uiHi
);

Parameters

msg [in]

Type: UINT

The DDE message to be posted.

A value that corresponds to the 16-bit Windows low-order word of an lParam parameter for the DDE message being posted.

uiHi [in]

Type: UINT_PTR

A value that corresponds to the 16-bit Windows high-order word of an lParam parameter for the DDE message being posted.

Return value

Type: LPARAM

The return value is the lParam value.

Remarks

The return value must be posted as the lParam parameter of a DDE message; it must not be used for any other purpose. After the application posts a return value, it need not perform any action to dispose of the lParam parameter.

An application should call this function only for posted DDE messages.
