INTER-PROCESS COMMNICATION What is Inter-process Communication? Inter-process communication as the name suggests is the exchange of information between two dependent /independent processes.   Why it is required? There are cases when processes may need to work together;for example a process … Continue reading →

Inter process communication using named pipes(FIFO) Earlier we saw the how to create pipes for communication between processes in linux. One of the major disadvantage of pipes is that the they can not be accesed using their names by any … Continue reading →

Fork (system call) fork is an operation whereby a process creates a copy of itself. It is usually a system call, implemented in the kernal. Fork is the primary (and historically, only) method of process creation on Unix-like operating systems.fork() … Continue reading →

SIGNALS: Signals were introduced by the first Unix systems to simplify interprocess communication.The kernel also uses them to notify processes of system events. In contrast to interrupts and exceptions, most signals are visible to User Mode processes. Also signals can … Continue reading →

Client Server using IPC   IPC stands for inter process communation and with help of this mechanism server can communicate with their appropriate clients. There are four types of IPC 1)Pipe 2)fifo 3)message queues 4)shared memory   pipe-It is mechanism … Continue reading →

A Linux System Programming using IPC. Many times for any client-server set-up to work efficiently, there arises a problem to share data or resources among various processes that are running. IPC involves many communication and synchronization techniques used to achieve … Continue reading →
