NAME <\/a> <\/h2>\n

wake_up \u2212 wake up sleeping processes<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

#include <\/b><\/p>\n\n\n
<\/td>\n\n

void wake_up(struct\u00a0wait_queue**<\/b>condition<\/i>)<\/b><\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

DESCRIPTION <\/a> <\/h2>\n

The wake_up<\/b> function is the opposite of the sleep_on<\/b>(9) function in that it awakens processes that have gone to sleep using the same condition variable. All the processes sleeping on the given condition are awakened. If there are no processes sleeping on the condition, then none are affected.<\/p>\n

Unlike the sleep_on<\/b>(9) function, wake_up<\/b> does not block and may be called by interrupt handlers. It is in fact the principle means of synchronizing with interrupt events.<\/p>\n

If the condition<\/i> parameter is NULL, or there are no processes sleeping on condition,<\/i> the call to wake_up<\/b> is a no-op.<\/p>\n

RETURN VALUE <\/a> <\/h2>\n

None.<\/p>\n

AVAILABILITY <\/a> <\/h2>\n
