How do I find the definition of a function?
In the Aaron Hillegass book (Cocoa Programming for Mac OSX), there is
an example that uses a function called fabs (on page 323). However,
there is no explanation of what this function does.
So in XCode 1.5, I option-clicked on "fabs" in some source code, and
HELP displayed the following information (from Apple's "Mathematical
and Logical Utilities Reference"):
---
fabs
double_t fabs (
double_t x
);
Parameter Descriptions
x
function result
See page for a description of the double_t data type.
Availability
Available in CarbonLib 1.0 and later when MathLib 1.0 or later is
present. Available in Mac OS X 10.0 and later.

Unfortunately the above documentation doesn't seem very helpful. What
does the function do? Why isn't there a description of what it does?
Where do I find an explanation of what "fabs" returns?
