Thread attributes are used to specify parameters to pthread_create(). One attribute object can be used in multiple calls to pthread_create(), with or without modifications between calls. The pthread_attr_init() function initializes attr with all the default thread attributes. The pthread_attr_destroy() function destroys attr. The pthread_attr_set*() functions set the attribute that corresponds to each function name. The pthread_attr_get*() functions copy the value of the attribute that corresponds to each function name to the location pointed to by the second function parameter. RETURN VALUES
If successful, these functions return 0. Otherwise, an error number is returned to indicate the error. ERRORS
pthread_attr_init() will fail if: [ENOMEM] Out of memory. pthread_attr_destroy() will fail if: [EINVAL] Invalid value for attr. pthread_attr_setstacksize() will fail if: [EINVAL] Invalid value for attr. [EINVAL] stacksize is less than PTHREAD_STACK_MIN. [EINVAL] stacksize is not a multiple of the system page size. pthread_attr_setdetachstate() will fail if: [EINVAL] Invalid value for attr or detachstate. pthread_attr_setinheritsched() will fail if: [EINVAL] Invalid value for attr. pthread_attr_setschedparam() will fail if: [EINVAL] Invalid value for attr. [ENOTSUP] Invalid value for param. pthread_attr_setschedpolicy() will fail if: [EINVAL] Invalid value for attr. [ENOTSUP] Invalid or unsupported value for policy. pthread_attr_setscope() will fail if: [EINVAL] Invalid value for attr. [ENOTSUP] Invalid or unsupported value for contentionscope. SEE ALSO
