NAME
       pthread_attr_init(), pthread_attr_destroy() - initialize or destroy a thread attributes object

SYNOPSIS
PARAMETERS
	      attr	Pointer to the thread attributes object to be initialized or destroyed.

DESCRIPTION
       initializes a thread attributes object attr with the default value for all the thread attributes.

       When  a	thread	attributes object is used to create a thread, the values of the individual attributes determine the characteristics of the
       new thread.  Attributes objects act like additional parameters to object creation. A single attributes object can be used in multiple calls
       to

       After  a  thread  attributes  object has been used to initialize one or more threads, any function affecting the attributes object does not
       affect the previously created threads.

       The thread attributes and their default values are:

	      stacksize 	POSIX.1c does not define a default value.  On HP-UX released on PA-RISC platforms, the default is 64K.	 On  HP-UX
				released on Itanium(R)-based platforms, the default is 256K.

	      guardsize 	The default value is bytes.

	      stackaddr 	The default value is NULL.

	      detachstate	The default value is

	      contentionscope	POSIX.1c  does not define a default value.  The default value is set to The scope can also be specified externally
				by using the options listed in the pthread_scope_options(5) manpage.

	      inheritsched	POSIX.1c does not define a default value. On HP-UX, the default value is

	      schedpolicy	POSIX.1c does not define a default value. On HP-UX, the default value is

	      schedparam	POSIX.1c does not define a default value.

	      processor 	The default value is

	      binding_type	The default value is

       If an initialized thread attributes object is reinitialized, the initialization results in undefined behavior.

       destroys the thread attributes object attr.  The destroyed thread attributes object ceases to exist and its resources are reclaimed. Refer-
       encing  the  object  after  it has been destroyed results in undefined behavior.  A destroyed thread attributes object can be reinitialized
       using thread attribute initialization routine

       Threads that have already been created using this attributes object are not affected by the destruction of the thread attributes object.

RETURN VALUE
       Upon successful completion, and return zero.  Otherwise, an error number is returned to indicate the error (the variable is not set).

ERRORS
       If any of the following occur, the function returns the corresponding error number:

	      [ENOMEM]	     There is insufficient memory available in which to initialize the pthread attributes object.

	      [EINVAL]	     The value specified by attr is invalid.

       If any of the following occur, the function returns the corresponding error number:

	      [EINVAL]	     The value specified by attr is invalid.
