NAME

pthread − Introduction to DCE Threads

DESCRIPTION

DCE Threads are a set of routines that you can call to create a multithreaded program. Multithreading is used to improve the performance of a program. 

The routines in this section are listed alphabetically. However, the the routines can be grouped according to the following categories:

       •Threads Routines

       •Attributes Object Routines

       •Mutex Routines

       •Condition Variable Routines

       •Per-Thread Context Routines

       •Thread Cancelation Routines

       •Thread Priority and Scheduling Routines

       •Cleanup Routines

Threads Routines

pthread_createCreates a Thread

pthread_delay_npCauses a Thread to Wait for a Period of Time

pthread_detachMarks a Thread for Deletion

pthread_exitTerminates the Calling Thread

pthread_joinCauses the Calling Thread to Wait for the Termination of a Specified Thread

pthread_onceCalls an Initialization Routine to be Executed Only Once

pthread_selfObtains the Identifier of the Current Thread

pthread_yieldNotifies the Scheduler that the Current Thread Will Release its Processor to Other Threads of the Same or Higher Priority
