Lists threads.

Syntax

#include <pthread.h>

Description

The pthread.h header defines the following symbols:

PTHREAD_CANCEL_ASYNCHRONOUS PTHREAD_CANCEL_ENABLE PTHREAD_CANCEL_DEFERRED 
PTHREAD_CANCEL_DISABLE PTHREAD_CANCELED PTHREAD_COND_INITIALIZER 
PTHREAD_CREATE_DETACHED PTHREAD_CREATE_JOINABLE PTHREAD_EXPLICIT_SCHED 
PTHREAD_INHERIT_SCHED PTHREAD_MUTEX_DEFAULT PTHREAD_MUTEX_ERRORCHECK 
PTHREAD_MUTEX_NORMAL PTHREAD_MUTEX_INITIALIZER PTHREAD_MUTEX_RECURSIVE 
PTHREAD_MUTEX_ROBUST PTHREAD_MUTEX_STALLED
PTHREAD_ONCE_INIT PTHREAD_PRIO_INHERIT PTHREAD_PRIO_NONE 
PTHREAD_PRIO_PROTECT PTHREAD_PROCESS_SHARED PTHREAD_PROCESS_PRIVATE 
PTHREAD_RWLOCK_INITIALIZER PTHREAD_SCOPE_PROCESS PTHREAD_SCOPE_SYSTEM

The pthread_attr_t, pthread_cond_t, pthread_condattr_t, pthread_key_t, pthread_mutex_t, pthread_mutexattr_t, pthread_once_t, pthread_rwlock_t, pthread_rwlockattr_t, and pthread_t types are defined as described in sys/types.h.

The following are declared as functions and may also be declared as macros. Function prototypes must be provided for use with an ISO C compiler.
