.Sh DESCRIPTION
|
|
The
|
|
.Fn ck_pr_load 3
|
|
family of functions atomically loads the value
|
|
pointed to by
|
|
.Fa target
|
|
and returns it. This family of functions always
|
|
serves as an implicit compiler barrier and is not
|
|
susceptible to re-ordering by the compiler.
|
|
.Sh RETURN VALUES
|
|
This family of functions returns the value contained
|
|
in the location pointed to by the first argument.
