as_set_priority()

void as_set_priority(unsigned as_off, 
                     unsigned priority);

Set the priority field of the indicated entry. If the AS_ATTR_CONTINUED bit is on in the entry, advance to the next entry in the section and set its priority as well (see as_add_containing() for why AS_ATTR_CONTINUED would be on). Repeat until an entry without AS_ATTR_CONTINUED is found.
