StoreBit

Psychtoolbox › PsychAlpha

oldBit=StoreBit([newBit])

Return the previously stored bit and, optionally, store a new bit.

StoreBit C source demonstrates how to call the OS X Cocoa API from a
mex file. StoreBit is not a practical means of storing bits in
MATLAB.

Because storing a bit in Cocoa is trivial, StoreBit's C source is the
almost-minimal architecture needed to call Cocoa from MATLAB.

The source code for StoreBit is divided between two targets:

1. StoreBit, within the main Psychtoolbox Xcode project, which builds
StoreBit.mexmac. StoreBit.mexmac does not contain Objective-C or
Cocoa calls. It loads the Cocoa bundle StoreBitLib, which does.

2. StoreBitLib, within the eponymous Xcode project StoreBitLib, which
builds the Cocoa bundle StoreBitBundle. The source includes
Objective-C wrapped within C. StoreBit.mexmac loads StoreBitLib and
invokes the C wrapper functions.
