|
|
* DOS/BIOS
|
|
* $ONELINER$
|
|
* Inform the operating system that the application is idle.
|
|
* $SYNTAX$
|
|
* FT_IAmIdle() -> lSuccess
|
|
* $ARGUMENTS$
|
|
* None
|
|
* $RETURNS$
|
|
* .T. if supported, .F. otherwise.
|
|
* $DESCRIPTION$
|
|
* Some multitasking operating environments (e.g. Windows or OS/2) can
|
|
* function more efficiently when applications release the CPU during
|
|
* idle states. This function allows you "announce" to the operating
|
|
* system that your application is idle.
|
|
*
|
|
* Note that if you use this function in conjunction with FT_OnIdle(),
|
|
* you can cause Clipper to automatically release the CPU whenever
|
|
* Clipper itself detects an idle state.
|
|
* $EXAMPLES$
|
|
* while inkey() != K_ESC
|
|
* FT_IAmIdle() // Wait for ESC and announce idleness
|
|
* end
|
|
*
|
|
* * Here's another way to do it:
|
|
*
|
|
* FT_OnIdle( {|| FT_IAmIdle()} )
|
|
*
|
|
* Inkey( 0 ) // Automatically reports idleness until key
|
|
* // is pressed!
|
|
* $SEEALSO$
|
|
* FT_OnIdle()
|
|
* $END$
