The POSIX Threads (pthreads) library provides various functions for multi-threading in C/C++ on UNIX-based systems. Here's a list of some commonly used functions in the pthreads API:

1. Thread Management

   • pthread_create(): Start a new thread.
   • pthread_exit(): Exit the current thread.
   • pthread_join(): Wait for a thread to finish.
   • pthread_detach(): Detach a thread so that it cleans up upon completion.
   • pthread_self(): Get the calling thread's ID.
   • pthread_equal(): Compare two thread IDs.

2. Mutex (Mutual Exclusion)

   • pthread_mutex_init(): Initialize a mutex.
   • pthread_mutex_destroy(): Destroy a mutex.
   • pthread_mutex_lock(): Lock a mutex.
   • pthread_mutex_trylock(): Try to lock a mutex without blocking.
   • pthread_mutex_unlock(): Unlock a mutex.

3. Condition Variables

   • pthread_cond_init(): Initialize a condition variable.
   • pthread_cond_destroy(): Destroy a condition variable.
   • pthread_cond_wait(): Block on a condition variable.
   • pthread_cond_signal(): Wake up one thread blocked on the condition variable.
   • pthread_cond_broadcast(): Wake up all threads blocked on the condition variable.
   • pthread_cond_timedwait(): Block on a condition variable for a specified time.

4. Thread Attributes

   • pthread_attr_init(): Initialize thread attributes.
   • pthread_attr_destroy(): Destroy thread attributes.
   • pthread_attr_setdetachstate(): Set the detach state attribute.
   • pthread_attr_getdetachstate(): Get the detach state attribute.
   • ... (There are many other attribute set/get functions for various attributes.)

5. Thread-specific Data

   • pthread_key_create(): Create a key for thread-specific data.
   • pthread_key_delete(): Delete a key for thread-specific data.
   • pthread_setspecific(): Set thread-specific data.
   • pthread_getspecific(): Get thread-specific data.

6. Scheduling

   • pthread_setschedparam(): Set scheduling parameters for a thread.
   • pthread_getschedparam(): Get scheduling parameters for a thread.
   • pthread_setschedprio(): Set the scheduling priority for a thread.

7. Read-Write Locks

   • pthread_rwlock_init(): Initialize a read-write lock.
   • pthread_rwlock_destroy(): Destroy a read-write lock.
   • pthread_rwlock_rdlock(): Read lock a read-write lock.
   • pthread_rwlock_wrlock(): Write lock a read-write lock.
   • pthread_rwlock_tryrdlock(): Try read lock without blocking.
   • pthread_rwlock_trywrlock(): Try write lock without blocking.
   • pthread_rwlock_unlock(): Unlock a read-write lock.

8. Spin Locks

   • pthread_spin_init(): Initialize a spin lock.
   • pthread_spin_destroy(): Destroy a spin lock.
   • pthread_spin_lock(): Lock a spin lock.
   • pthread_spin_trylock(): Try to lock a spin lock without blocking.
   • pthread_spin_unlock(): Unlock a spin lock.

9. Barrier

   • pthread_barrier_init(): Initialize a barrier.
   • pthread_barrier_destroy(): Destroy a barrier.
   • pthread_barrier_wait(): Wait on a barrier.

10. Cancellation

    • pthread_setcancelstate(): Set the cancelability state of the current thread.
    • pthread_setcanceltype(): Set the cancellation type of the current thread.
    • pthread_cancel(): Request cancellation of a thread.
    • pthread_testcancel(): Create a cancellation point in the calling thread.

This list is a broad overview of the pthreads API, but it provides a glimpse of the variety of functions available for multithreaded programming.
