PtUpdate()

Decrement the global hold count

Synopsis:

int PtUpdate( void );

Library:

Description:

This function decrements the global widget hold count, which was previously incremented by a call to PtHold(). When the count reaches 0, the widgets are repaired.

This function is the same as PtRelease().

PtHold() and PtRelease() affect all widgets, while PtContainerHold() and PtContainerRelease(), prevent only child widgets of a container from being repaired.

Returns:

The current hold count, or -1 if an error occurred.
