postwait(2) System Calls Manual postwait(2)
NAME
postwait: pw_getukid(), pw_wait(), pw_post(), pw_postv(), pw_getvmax() - lightweight synchronization mechanism
SYNOPSIS
DESCRIPTION
Postwait is a fast, lightweight sleep/wakeup mechanism that can be used for synchronization by cooperating kernel threads within a single
process or between separate processes.
A thread calls to block. It resumes execution when it is posted by another thread, the call expires, or is signaled. If one or more posts
are already pending, returns immediately.
Threads using postwait are identified by their ukid. A thread retrieves its ukid by calling It shares this ukid with anyone it chooses by
any means it considers appropriate (for example, shared memory).
is called with a timeout ts. If ts is NULL, the thread will not timeout. It will remain blocked until posted or a signal wakes it up.
If ts points to a zero-valued timespec, will return immediately with a value (and indicating whether or not it was posted.
If ts points to a timespec whose value is greater than zero, the thread will block for that amount of time unless it is posted or inter-
rupted by a signal, in which case the timespec pointed to by ts is updated with the remaining time. The return value and are set to indi-
cate the reason the call returned.
is used to post many threads with a single call. It posts to all threads in the targets array. An value for each target is returned in
the errors array. (0 indicates success.) If the errors pointer is zero, no target-specific errors are copied out.
There is a maximum number of threads that can be posted with a single call. This value is returned by
Posts sent to a kernel thread that already has a post pending against it are discarded.
RETURN VALUE
returns 0 if it succeeds, -1 otherwise.
returns 0 if posted, -1 otherwise.
returns 0 if the post succeeds, -1 otherwise.
returns 0 if every post succeeds, -1 otherwise.
returns the maximum number of kernel threads that can be posted with a single call to
