Attributes Objects for Threads

• pthread_attr_init;

  
• This function initializes the attributes object attr to the default values.
• Upon successful completion, the function returns a 0, otherwise it returns an error code.
• The attributes object may be destroyed.
• pthread_attr_destroy;

  
• The call returns a 0 on successful removal of the attributes object attr.

• Individual properties associated with the attributes object can be changed using the following functions:
• pthread_attr_setdetachstate $\Longrightarrow$ to set the detach state
• pthread_attr_setguardsize_np $\Longrightarrow$ to set the stack guard size
• pthread_attr_setstacksize $\Longrightarrow$ to set the stack size
• pthread_attr_setstackaddr $\Longrightarrow$ to set the stack address
• pthread_attr_setinheritsched $\Longrightarrow$ to set whether scheduling policy is inherited from the creating thread
• pthread_attr_setschedpolicy $\Longrightarrow$ to set the scheduling policy (in case it is not inherited)
• pthread_attr_setschedparam $\Longrightarrow$ to set the scheduling parameters
• pthread_attr_setprio $\Longrightarrow$ to set the priority
• pthread_attr_default, pthread_attr_init
• For most parallel programs, default thread properties are generally adequate.
