the lights</title><prolog><metadata><keywords/></metadata></prolog><taskbody>

<context>       <p>The <codeph>ReserveLightL()</codeph> call reserves the

light target(s) exclusively for this client. Multiple lights can be specified

by using bitwise-or. A higher priority client may cause lower priority client

reservation to be temporarily suspended. Commands can still be issued in suspended

state, but they are not acted upon unless suspension is lifted within a specified

duration. The suspended client does not get any notification about suspension.

If the light target is already reserved by a higher or equal priority application,

reserving still succeeds, but the reservation is immediately suspended.</p><p>The

following code snippet demonstrates how to reserve multiple light targets:</p><codeblock xml:space="preserve">//aRestoreState = ETrue means that any previously frozen state will be restored.

// aForceNoCCoeEnv = EFalse means that the CCoeEnv background/foreground status

// is always used to control further reservations.

iLight-&gt;ReserveLightL( ( CHWRMExtendedLight::EPrimaryDisplay | CHWRMExtendedLight::EPrimaryKeyboard ), ETrue, EFalse );</codeblock></context>
