All processes have a processing environment (not to be confused with environment variables that are, as we will see, just one part of the processing environment). The processing environment consists of a unique set of information and conditions that is determined by the current state of the system and by the parent of the process. A process can access processing environment information and, in some cases, modify it. This is accomplished either directly or by using the appropriate system calls or library functions.
