PTHREAD_ATTR_INIT(3) BSD Programmer's Manual PTHREAD_ATTR_INIT(3)
pthread_attr_init, pthread_attr_destroy - initialise and destroy threads attribute object
#include <pthread.h> int pthread_attr_init(pthread_attr_t *attr); int pthread_attr_destroy(pthread_attr_t *attr);
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.
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.
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].
