DESCRIPTION¶
The
ck_pr_fas
(
3)
family of functions atomically fetch the value pointed to by
target and replace the value pointed to by
target with the value specified by
new_value.
RETURN VALUES¶
This function returns the value pointed to by
target at the time of operation invocation
before it was atomically replaced with
new_value.
