A few of the common socket options are: SO_REUSEADDR:This is to report whether the same port can be reused again that is socket can be bind to the same port or not. This is a Boolean option. SO_KEEPALIVE:This is to… Read More ›
Operating system (OS)
An operating system is system software that manages computer hardware, software resources, and provides common services for computer programs.
Socket Programming
Client-Server communication Sockets Procedures socket() : Create a socket bind(): Name a socket connect(): Request a connection listen(): Listen for a new connection accept(): Accept a new connection send()/sendto(): Send data over connection recv()/recvfrom(): Recv data over communication close(): Close… Read More ›
Scheduling metrics and algorithm
Scheduling metrics helps in measuring any scheduling algorithm. The two most important scheduling metrics are: Turnaround Time and the Response Time Turnaround Time:The turnaround of a job is defined as the time at which the job completes minus the time… Read More ›
Preemptive vs NON-PREEMPTIVE SCHEDULING
CPU scheduling is the process of selecting the next process to be allocated to the CPU whenever the CPU becomes idle because of execution of another process is on hold(waiting state) due to the unavailability of any resources like I/O…. Read More ›
Destroy a Mutex
The pthread_mutex_destroy() API is used to destroy the mutex object referenced by mutex. Prototype: The pthread_mutex_destroy() function shall destroy the mutex object referenced by mutex; the mutex object becomes, in effect, uninitialized. The mutex must not be used after it… Read More ›
Unlock a Mutex
The pthread_mutex_unlock() API is used to unblock the mutex reference by mutex. Prototype: The pthread_mutex_unlock() function releases the mutex object referenced by mutex. The manner in which a mutex is released is dependent upon the mutex type attribute. If there… Read More ›
Lock a Mutex
The pthread_mutex_lock API is used to lock the mutex referenced by mutex. Prototype: This API is used to lock the mutex object referenced by mutex. If the mutex is already locked, the calling thread is blocked until the mutex becomes… Read More ›
Initialize a Mutex
The pthread_mutex API is used to initialize the mutex referenced by mutex with attributes specified by attr. Prototype: The first argument is the mutex that need to be initialized. The second argument is the attribute pointer which can be NULL… Read More ›
Named pipe vs socket
In a fast local area network (LAN) environment, Transmission Control Protocol/Internet Protocol (TCP/IP) Sockets and Named Pipes clients are comparable in terms of performance. For named pipes, network communications are typically more interactive. A peer does not send data until… Read More ›
Broken pipe error(SIGPIPE)
SIGPIPE is the “broken pipe” signal that the kernel generates when a process writes to a pipe that has been closed by the reader, by default this causes the process terminates. This behavior is useful for typical cases of running… Read More ›
