1. In the project builder, I cannot set the arguments to the program
while debugging. In the debugger console, I did as follows:
set args ~/hello
run
However, the command line options was not set.
But if I used gdb on a terminal, with the same method, the command
line was set to the program. How to assign command line options to the
program debugged in Project Builder?
Click the Targets panel in the left, find your program in Executables,
click it, and then you can add launch arguments there.
It sounds like PB is overriding the arguments you're entering manually.
2. Another strange and stupid question is Option-double-click does not
work. For example, I need to access the documentation for
AudioAddIOProc in the editor of Project Builder, I pressed the option
key on the keyboard and the double click the mouse on AudioAddIOProc,
there is no documentation poped up. How to do that?
Try command-double-clicking.
3. This question is related to Audio device, what is the difference
between "Physical format" and "format" for a channel. To be straight,
with DisplayHALDeviceInfo from /Developer/Example/CoreAudio,
The physical format is the format of the samples the driver is actually
working with. You generally don't need to know this (there are a few
situations where it may be useful, but at least for getting started,
there's no reason to be concerned with it.
The (plain) format is the format of the samples that you send/receive
in your IOProc.

Thanks for help and tolerating these stupid questions,:)
