PTHREAD_ATTR_INIT(3) Library Functions Manual PTHREAD_ATTR_INIT(3)

NAME

pthread_attr_init, pthread_attr_destroyinitialise 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 attributes 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 attributes object.
These functions will not return an error code of [EINTR].

STANDARDS

pthread_attr_destroy() and pthread_attr_init() conform to ISO/IEC 9945-1 ANSI/IEEE (“POSIX”) Std 1003.1 Second Edition 1996-07-12.
