WINHLLAPI LANGUAGE REFERENCE Function 12: Release This function unlocks a PS that was reserved using Function 11, “Reserve.” The target is the currently connected PS. Release also occurs automatically when the client application program calls Function 2, “Disconnect Presentation Space”; Function 1, “Connect Presentation Space”; Function 21, “Reset System”; or terminates, or the session itself is terminated. Because release occurs automatically on disconnect, it is not crucial that you use the Release function whenever you end an application. Prerequisites Function 1, “Connect Presentation Space.” Applicable session parameters None. Call parameters An application program must pass the following parameters when calling this function: Function 12 Data string Data length PS position Not applicable. Not applicable. Reserved.
