pthread_create

PTHREAD_CREATE(3) PTHREAD_CREATE(3)

NAME pthread_create - create a new thread

SYNOPSIS #include <pthread.h>

int pthread_create(pthread_t * thread, pthread_attr_t * attr, void * (*start_routine)(void *), void * arg);

DESCRIPTION pthread_create creates a new thread of control that executes concurrently with the calling thread. The new thread applies the function start_routine passing it arg as first argument. The new thread terminates either explicitly, by calling pthread_exit(3), or implicitly, by returning from the start_routine function. The latter case is equivalent to calling pthread_exit(3) with the result returned by start_routine as exit code.

The attr argument specifies thread attributes to be applied to the new thread. See pthread_attr_init(3) for a complete list of thread attributes. The attr argument can also be NULL, in which case default attributes are used: the created thread is joinable (not detached) and has default (non real-time) scheduling policy.

RETURN VALUE On success, the identifier of the newly created thread is stored in the location pointed by the thread argument, and a 0 is returned. On error, a non-zero error code is returned.

ERRORS EAGAIN not enough system resources to create a process for the new thread.

EAGAIN more than PTHREAD_THREADS_MAX threads are already active.
