NAME

pthread.h - threads

SYNOPSIS



#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_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.

Inclusion of the <pthread.h> header will make visible symbols defined in the headers <sched.h> and <time.h>.

APPLICATION USAGE

An interpretation request has been filed with IEEE PASC concerning requirements for visibility of symbols in this header.

FUTURE DIRECTIONS

None.
