PTHREAD_ATTR_INIT(3)       BSD Programmer's Manual        PTHREAD_ATTR_INIT(3)

NAME

     pthread_attr_init, pthread_attr_destroy - initialise and destroy threads
     attribute object

SYNOPSIS

     #include <pthread.h>

     int
     pthread_attr_init(pthread_attr_t *attr);

     int
     pthread_attr_destroy(pthread_attr_t *attr);

DESCRIPTION

     The function pthread_attr_init() initialises a thread attributes object
     attr with the default value for all of the individual attributes used by
     a given implementation.

     The resulting attribute object (possibly modified by setting individual
     attribute values), when used by pthread_create(3), defines the attributes
     of the thread created. A single attributes object can be used in multiple
     simultaneous calls to pthread_create(3).

     The pthread_attr_destroy() function is used to destroy a thread attri-
     butes object. An implementation may cause pthread_attr_destroy() to set
     attr to an implementation-dependent invalid value. The behaviour of using
     the attribute after it has been destroyed is undefined.

RETURN VALUES

     Upon successful completion, pthread_attr_init() and
     pthread_attr_destroy() return a value of 0. Otherwise, an error number is
     returned to indicate the error.

ERRORS

     The pthread_attr_init() function will fail if:

     [ENOMEM]      Insufficient memory exists to initialise the thread attri-
                   butes object.

     These functions will not return an error code of [EINTR].

STANDARDS

     pthread_create() conforms to ISO/IEC 9945-1 ANSI/IEEE ("POSIX") Std
     1003.1 Second Edition 1996-07-12.
