# Bounds-checking Integer Arithmetic
|
||
|
|
|
||
|
|
GLib offers a set of macros for doing additions and multiplications
|
||
|
|
of unsigned integers, with checks for overflows.
|
||
|
|
|
||
|
|
The helpers all have three arguments. A pointer to the destination
|
||
|
|
is always the first argument and the operands to the operation are
|
||
|
|
the other two.
|
||
|
|
|
||
|
|
Following standard GLib convention, the helpers return true in case
|
||
|
|
of success (ie: no overflow).
|
||
|
|
|
||
|
|
The helpers may be macros, normal functions or inlines. They may be
|
||
|
|
implemented with inline assembly or compiler intrinsics where
|
||
|
|
available.
|
||
|
|
|
||
|
