Thread functions in C/C++ - GeeksforGeeks
2023年5月9日 · pthread_self: used to get the thread id of the current thread. Syntax: pthread_t pthread_self(void); pthread_equal: compares whether two threads are the same or not. If the two threads are equal, the function returns a non-zero value otherwise zero. Syntax: int pthread_equal(pthread_t t1, pthread_t t2);
Multithreaded Programming (POSIX pthreads Tutorial) - randu.org
pthread_cond_wait() puts the current thread to sleep. It requires a mutex of the associated shared resource value it is waiting on. pthread_cond_signal() signals one thread out of the possibly many sleeping threads to wakeup. pthread_cond_broadcast() signals all threads waiting on the cond condition variable to wakeup. Here is an example on ...
POSIX Threads in OS - GeeksforGeeks
2022年12月10日 · POSIX Threads in OS. The POSIX thread libraries are a C/C++ thread API based on standards. It enables the creation of a new concurrent process flow. It works well on multi-processor or multi-core systems, where the process flow may be scheduled to execute on another processor, increasing speed through parallel or distributed processing.
Multithreading in C - GeeksforGeeks
2024年10月11日 · In main(), we declare a variable called thread_id, which is of type pthread_t, which is an integer used to identify the thread in the system. After declaring thread_id, we call pthread_create() function to create a thread. pthread_create() takes 4 arguments. The first argument is a pointer to thread_id which is set by this function.

Conditional wait and signal in multi-threading - GeeksforGeeks
2023年1月27日 · In C under Linux, there is a function pthread_cond_wait () to wait or sleep. On the other hand, there is a function pthread_cond_signal () to wake up sleeping or waiting thread. Threads can wait on a condition variable. Prerequisite : Multithreading. Syntax of pthread_cond_wait () : pthread_mutex_t *restrict mutex);
Mutex lock for Linux Thread Synchronization - GeeksforGeeks
2024年5月24日 · int pthread_mutex_lock (pthread_mutex_t *mutex) : Locks a mutex object, which identifies a mutex. If the mutex is already locked by another thread, the thread waits for the mutex to become available. The thread that has locked a mutex becomes its current owner and remains the owner until the same thread has unlocked it.
pthread_equal() in C with example - GeeksforGeeks
2019年10月14日 · pthread_equal () = This compares two thread which is equal or not. This function compares two thread identifiers. It return ‘0’ and non zero value. If it is equal then return non zero value else return 0. Syntax:- int pthread_equal (pthread_t t1, pthread_t t2); First Method :- Compare with self thread. Output:
Thread in Operating System - GeeksforGeeks
2024年6月27日 · A thread is a single sequence stream within a process. Threads are also called lightweight processes as they possess some of the properties of processes. Each thread belongs to exactly one process. In an operating system that supports multithreading, the process can consist of many threads. But threads can be effective only if the CPU is more ...
