Using these functions
These functions each map onto a C++ function. C++ allows "pass by reference", which lets you pass a variable to a function in the parameter list and have the function change that parameter, so after this function call:
x = MyFunc(&var);
the var variable might well have a different value to the one it started with...
Perl and Python don't have compatible pass by reference mechanisms so when ReaScript sees a modifiable variable in the parameter list it returns all the values in the parameter list and the return value (if there is one) in an array, as in GetUserInputs() Go and look at it now if you haven't already done so. It will bite you if you don't understand it.
Specific REAPER type pointers, like MediaItem*, are not considered modifiable by ReaScript when deciding whether to return a scalar or array from a particular function.
Who is Allowed to Add to and Edit this Documentation?
You.
No, really - you are. Don't hesitate to get stuck in if you think you know something that even might be of help to some poor muso feeling his or her way around the API.
Anything in the API documentation that is marked with a '?' is an assumption - or something the writer just isn't sure about. If you happen to know whatever it is for certain - please correct or confirm the entry.
Please add a brief note or correction if you see anything that's wrong or incomplete or if you've used the function and know something that might be of use to the next user.
Don't worry about making it look good if you're hurried; someone will be along in a while with the time. (Don't hesitate to make it look good if you *do* have the time... :o)
