dynamic allocation of NSPoints array

[Joe]

I don't know how large my NSPointArray size needs to be so I'd like to
know how I would dynamically allocate NSPoints to populate an
NSPointArray? I think I can do it with NSMutableArray, but NSBezierPath
takes an NSPointArray (which is what my end result is for the points)
and it just seems cleaner and more efficient if I can stay with that
instead of converting between point arrays and mutable arrays.

typedef NSPoint *NSPointArray;

That means an NSPointArray is a pointer to NSPoint structures.
Just follow the rules of allocating dynamic C arrays.

[Jason Sikes]

In these situations I often use C++'s vectors. Example:

std::vector<NSPoint> myPointAry;

Vectors in C++ are contiguous
...Fill your array. Then when you need the NSPointArray, cast it
thusly...

[myBezierPath appendBezierPathWithPoints:(NSPointArray) &myPointAry[0]
count:10];

myPointAry[0] of course is the first element of the vector.
&myPointAry[0] is a pointer to the first element of the vector.
Since we know that the rest are contiguous, you have a C array of
NSPoints.
And C++ manages dynamic memory allocation for you. It's quite
efficient.
