1.0 POSIX threads A process is an execution environment in an operating system. A process has code and data segments which are initialized from a program during an exec system…
POSIX Semaphores in Linux
1.0 Semaphores Semaphores are used for process and thread synchronization. Semaphores are clubbed with message queues and shared memory under the Interprocess Communication (IPC) facilities in Unix-like systems such as…
System V Semaphores in Linux
1.0 Semaphores A semaphore is a mechanism for synchronizing processes and threads. Semaphore, in Unix-like systems, are provided under interprocess communication (IPC) facilities along with message queues and shared memory.…
POSIX message queues in Linux
POSIX message queue calls for interprocess communication (IPC) between processes are explained with an example of server and client programs in C under Linux.
System V message queues in Linux
1.0 Message queues Message queues are one of the interprocess communication mechanisms available under Linux. Message queues, shared memory and semaphores are normally listed as the three interprocess communication mechanisms…
