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].
