FtrGet retrieves a 32-bit integer that you store previously using FtrSet.

depends on what the value of foo is.. :)

this will only work if SomeDataType = 32 bits :)
normally, you use as follows:
// get the data
SomeDataType *value;
err = FtrGet(appFileCreator, ftrNum, (UInt32 *)value);
and you store as:
// set the data
SomeDataType value;
err = FtrSet(appFileCreator, ftrNum, (UInt32)&value);
normally, you set once.. and, get many times :) it depends what you
are using the feature for :P got the idea? i believe my sample code
(cube3d/burning) use features..
