Detailed Description

Definitions for general use.

Macro Definition Documentation

#define KILOBYTE   0x400

Kilobyte.

Typically a multiplier.

#define MEGABYTE   0x100000

Megabyte.

Typically a multiplier.

#define TIME_WAIT_FOREVER   0xffffffff

Wait forever.

Many macros or functions with a timeout parameter will accept this value to represent an indefinite period of time.
