Module sync 

Modules

broadcast

A multi-producer, multi-consumer broadcast queue. Each sent value is seen by all consumers.

mpsc

A multi-producer, single-consumer queue for sending values between asynchronous tasks.

oneshot

A one-shot channel is used for sending a single message between asynchronous tasks. The channel function is used to create a Sender and Receiver handle pair that form the channel.

Structs

Arc

A thread-safe reference-counting pointer. ‘Arc’ stands for ‘Atomically Reference Counted’.

Mutex

An asynchronous Mutex-like type.

MutexInfo

One row of C’s epicsMutexShow (epicsMutex.cpp:118-127).

MutexReport

What C prints from one epicsMutexShowAll call: the whole list’s length, then the rows that passed onlyLocked.

Notify

Notifies a single task to wake up.

RwLock

An asynchronous reader-writer lock.

Constants

MUTEX_OSD_LABEL

See MUTEX_OSD_LABEL.

Functions

is_pi_mutex_active

Diagnostic — true when the PI variant is active in this build.

mutex_report

Every EPICS mutex in the process, filtered as C’s onlyLocked filters — epicsMutexShowAll’s list walk.

osd_show_all_line

C epicsMutexOsdShowAll (os/posix/osdMutex.c:197-210), the line epicsMutexShowAll prints between the count and the rows.

report_lock_protocol

Print, once at boot, which lock protocol this process actually obtained.

Type Aliases

PriorityInheritanceMutex

C epicsMutexId — the mutex every EPICS lock in this port is built from, and the only one epicsMutexShowAll can see.

PriorityInheritanceMutexGuard

See PriorityInheritanceMutexGuard — parking_lot’s guard is already !Send for the same reason.
