NetBSD 6.1.5 - man page for pthread_attr_init (netbsd section 3)

PTHREAD_ATTR(3) 		   BSD Library Functions Manual 		  PTHREAD_ATTR(3)

NAME
     pthread_attr_init, pthread_attr_destroy -- thread attribute operations

LIBRARY
     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS
     #include <pthread.h>

     int
     pthread_attr_init(pthread_attr_t *attr);

     int
     pthread_attr_destroy(pthread_attr_t *attr);

DESCRIPTION
     Thread attributes are used to specify parameters to pthread_create().  One attribute object
     can be used in multiple calls to pthread_create(), with or without modifications between the
     calls.  The pthread_attr_t type is an opaque representation of the thread attributes; any
     access to the object other than via the described pthread_attr_*() functions may result in
     undefined behavior.

     The pthread_attr_init() function initializes attr with the default thread attributes used in
     the implementation.  Depending on the implementation, undefined behavior may follow if an
     uninitialized thread attribute object is used with some of the thread attribute functions.
     It is therefore a good practice to always use pthread_attr_init(), even if this might be
     unnecessary.  Undefined behavior may also follow if an already initialized attr is used with
     pthread_attr_init().

     When the attribute object is no longer needed, it should be destroyed by using
     pthread_attr_destroy().  The function has no effect on threads that were created by using a
     given attribute object.  A destroyed attr can be reinitialized using pthread_attr_init(),
     but all other actions with the destroyed object are unspecified.

     The following standard thread attribute functions are available:

	   Function			    Description
	   pthread_attr_getdetachstate(3)   thread detach state
	   pthread_attr_getguardsize(3)     thread guard size
	   pthread_attr_getinheritsched(3)  inherit scheduler attribute
	   pthread_attr_getschedparam(3)    thread scheduling parameter
	   pthread_attr_getschedpolicy(3)   thread scheduling policy
	   pthread_attr_getscope(3)	    thread contention scope
	   pthread_attr_getstack(3)	    thread stack
	   pthread_attr_getstacksize(3)     thread stack size
	   pthread_attr_getstackaddr(3)     thread stack address

     Each listed pthread_attr_get*() function contains a pthread_attr_set*() counterpart.  In
     addition, the following NetBSD specific extensions are available:

	   Function			    Description
	   pthread_attr_get_np(3)	    attributes of a running thread
	   pthread_attr_getname_np(3)	    descriptive name of an attribute

RETURN VALUES
     If successful, these functions return 0.  Otherwise, an error number is returned to indicate
     the error.

ERRORS
     No errors are defined for pthread_attr_init() and pthread_attr_destroy().

SEE ALSO
     pthread_create(3), pthread_join(3)

STANDARDS
     Both pthread_attr_init() and pthread_attr_destroy() conform to IEEE Std 1003.1-2001
     (``POSIX.1'').
