LINE INPUT will now use the faster method if passed a file handle that has been opened FOR BINARY. As such, the _BLINEINPUT command has been removed. qb64.bas now takes advantage of this for reading from '$include files, at least in Include Manager 1. Some tweaking of internal/source/main.txt was required to get things into a sane state, so I'm holing off changing the compiler any further so the auto-builder can make sure everything's smoothed over. Note: Everything should still compile as normal; I'm just being overcautious.

The '''_SNDRAWLEN''' function returns the length, in seconds, of a [[_SNDRAW]] sound currently queued.

:: length# = _SNDRAWLEN
|
|
|
|
|
|
* Use the _SNDRAWLEN to determine the length of a sound queue during creation and when to stop playing the sound.
|
|
* Ensure that _SNDRAWLEN is comfortably above 0 (until you've actually finished playing sound).
|
|
* If you are getting occasional random clicks, this generally means that _SNDRAWLEN has dropped to 0.
|
|
* The [[_SNDRATE]] determines how many samples are played per second. However, the timing is achieved by the sound card and the _SNDRAWLEN, not your program!
|
|
* '''Do NOT attempt to use [[_TIMER]] or [[_DELAY]] or [[_LIMIT]] to control the timing of [[_SNDRAW]] sounds! You may use them as usual for delays or to limit your program's CPU usage, but the decision of how much sound to queue should only be based on the _SNDRAWLEN!'''
