The operating system does not release the resources allocated to a socket until the socket is closed. This is especially important if the connect call fails and will be retried. When an application closes a socket, only the interface to the socket is destroyed. It is the kernel's responsibility to destroy the socket internally.
Resolving resource contention problems is one of the basic functions of operating systems. Various low-level mechanisms can be used to aid this, including locks, semaphores, mutexes and queues. The other techniques that can be applied by the operating systems include intelligent scheduling, application mapping decisions, and page coloring. [1] [2]
In Unix and other POSIX-compatible systems, the parent process can retrieve the exit status of a child process using the wait() family of system calls defined in wait.h. [10] Of these, the waitid() [ 11 ] call retrieves the full exit status, but the older wait() and waitpid() [ 12 ] calls retrieve only the least significant 8 bits of the exit ...
The application programming interface (API) for the network protocol stack creates a handle for each socket created by an application, commonly referred to as a socket descriptor. In Unix-like operating systems, this descriptor is a type of file descriptor. It is stored by the application process for use with every read and write operation on ...
Some operating systems, such as Linux and HP-UX, [citation needed] implement a half-duplex close sequence. If the host actively closes a connection, while still having unread incoming data available, the host sends the signal RST (losing any received data) instead of FIN. This assures that a TCP application is aware there was a data loss. [34]

In computing, logging is the act of keeping a log of events that occur in a computer system, such as problems, errors or just information on current operations. These events may occur in the operating system or in other software. A message or log entry is recorded for each such event.
Netlink is a socket family used for inter-process communication (IPC) between both the kernel and userspace processes, and between different userspace processes, in a way similar to the Unix domain sockets available on certain Unix-like operating systems, including its original incarnation as a Linux kernel interface, as well as in the form of a later implementation on FreeBSD.
