(v13) SwLePgbSetCallback

This page applies to Harlequin v13.1r0 and later; and to Harlequin Core but not Harlequin MultiRIP.

Sets a callback function for the pagebuffer device parameter. If a callback function is registered correctly, it will be called whenever the value of a pagebuffer device parameter is changed. There is one callback for each parameter and setting the callback overrides the previous callback definition. To remove a callback hook, call this function with a NULL function pointer. The parameter name to monitor is paramname and paramtype is the type of the parameter name to monitor. pfnPGBCallback is a pointer to a function through which the RIP informs the skin of pagebuffer parameter changes. The skin may call SwLeSetCallbacks in this routine, to route callbacks to different backends. It returns FALSE If the callback could not be set or TRUE If the callback was set.
