PAGE 2
pthread_attr_getdetachstate(3T) pthread_attr_getdetachstate(3T) (Pthread Library) PARAMETERS attr Pointer to the thread attributes object whose attributes are to be set/retrieved. detachstate This parameter either specifies the new value of the detachstate attribute (set function) or it points to the memory location where the detachstate attribute of attr is to be returned (get function).
PAGE 3
pthread_attr_getdetachstate(3T) pthread_attr_getdetachstate(3T) (Pthread Library) pthread_attr_setschedpolicy() - set the schedpolicy attribute. pthread_attr_getschedpolicy() - get the schedpolicy attribute. pthread_attr_setschedparam() - set the schedparam attributes. pthread_attr_getschedparam() - get the schedparam attributes. pthread_attr_setscope() - set the contentionscope attribute. pthread_attr_getscope() - get the contentionscope attribute.
PAGE 4
pthread_attr_getdetachstate(3T) pthread_attr_getdetachstate(3T) (Pthread Library) ATTRIBUTE: rsestacksize The legal values for the rsestacksize are: rsestacksize This defines the size (in bytes) of the register stack for the threads created with the attributes object. pthread_attr_setrsestacksize_np() is used to set the register stack size for a thread and pthread_default_rsestacksize_np() to set the default register stack size.
PAGE 5
pthread_attr_getdetachstate(3T) pthread_attr_getdetachstate(3T) (Pthread Library) PTHREAD_EXPLICIT_SCHED This option specifies that the scheduling policy and associated attributes for the created thread(s) are to be taken from this attributes object. These values will not be inherited from the creating thread. POSIX.1c does not define a default value for the inheritsched attribute. On HP-UX, the default value is PTHREAD_INHERIT_SCHED.
PAGE 6
pthread_attr_getdetachstate(3T) pthread_attr_getdetachstate(3T) (Pthread Library) ATTRIBUTES: processor and binding_type The legal values for the processor attribute are: PTHREAD_SPUINHERIT_NP Threads created with this processor attribute inherit their processor binding attributes from the creating thread. This is the default value of the processor attribute. Specifying PTHREAD_LDOMINHERIT_NP or PTHREAD_SPUINHERIT_NP cause both processor binding and locality domain binding attributes to be inherited.
PAGE 7
pthread_attr_getdetachstate(3T) pthread_attr_getdetachstate(3T) (Pthread Library) pthread_attr_setprocessor_np() is used to set the processor and binding_type attributes in the initialized attributes object attr . The new values of the processor and binding_type attributes are passed to this function in the processor and binding_type parameters, respectively. pthread_attr_getprocessor_np() retrieves the values of the processor and binding_type attributes from the thread attributes object attr .
PAGE 8
pthread_attr_getdetachstate(3T) pthread_attr_getdetachstate(3T) (Pthread Library) [EINVAL] detachstate , guardsize , inheritsched , processor , binding_type , policy , param , or scope contains an invalid value. [ENOTSUP] The value contained in policy is not a supported value. [ENOSYS] pthread_attr_setrsestacksize_np() and pthread_attr_getrsestacksize_np() are not supported on PA-RISC systems.
