.Sh NAME

.Nm ck_epoch_begin

.Nd begin epoch-protected segment of execution
|

Concurrency Kit (libck, \-lck)

|
.Sh SYNOPSIS
|
||
|
|
.In ck_epoch.h
|
||
|
|
|
||
|
|
.Ft void
|
||
|
|
.Fn ck_epoch_begin "ck_epoch_t *epoch" "ck_epoch_record_t *record"
|
||
|
|
.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Fn ck_epoch_begin 3
|
||
|
|
function will mark the beginning of an epoch-protected code section.
|
||
|
|
An epoch-protected code section is delimited by a call to the
|
||
|
|
.Fn ck_epoch_end 3
|
||
|
|
function. Though recursion is allowed for epoch-protected sections,
|
||
|
|
recursive calls will be associated with the
|
||
|
|
.Fn ck_epoch_begin 3
|
||
|
|
that is at the top of the call stack.
|
||
|
|
.Sh RETURN VALUES
|
||
|
|
This function has no return value.
|
||
|
|
.Sh ERRORS
|
||
|
|
The object pointed to by
|
||
|
|
.Fa epoch
|
||
|
|
must have been previously initiated via
|
||
|
|
.Fn ck_epoch_init 3 .
|
||
|
|
The object pointed to by
|
||
|
|
.Fa record
|
||
|
|
must have been previously registered via
|
||
|
|
.Fn ck_epoch_register 3 .
