Interprocess Communication with macOS: Apple IPC Methods
Description :
Build highly modular software in macOS that interacts deeply and
intuitively with other programs. This book explores all techniques
available for Inter-process communications(IPC) from high level

macOS layers to deep kernel options while applying theoretical
concepts into practical implementations on real world
scenarios.You'll see how IPC techniques are used for exchanging
data and messages among multiple threads in one or more
processes, which may be running on one or more computers
connected by a network or running locally. IPC methods can be
divided into methods for message passing, synchronization, shared
memory, and remote procedure calls (RPC). A poorly
conceivedIPCcan even expose an entire network to over-the-network
attacks. Despite the risks, processes and applications absolutely
need to communicate with each other across your system and the
network. You'll see how these communications facilitate information
sharing, computational speedup, modularity, convenience, and
privilege separation.InmacOS, a program has a number of ways to
communicate with other programs. These mechanisms forIPC often
exist in different layers of the system. You'll examine how each has
its own specific purposes, limitations, and intended scenarios. Some
are more suitable than others for code written at a certain level of
the system. For example, a kernel extension would not make use of
Apple events.Additionally, the book reveals that different users have
different rights when it comes to accessing files, changing system
wide settings, and so on, depending on whether they are admin
users or ordinary users. Running code with root or
administrativeprivileges can intensify the dangers posed by security
vulnerabilities. You'll learn that to elevate privileges safely, it is
mandatory for the application to perform the task through a secure
Helper process.What You'll LearnExpand the capabilities of your
