|
|
|
|
|
The
|
|
|
|
|
.Fn ck_pr_inc 3
|
|
|
|
|
family of functions atomically increment the value pointed to
|
|
|
|
|
by
|
|
|
|
|
.Fa target .
|
|
|
|
|
.Sh RETURN VALUES
|
|
|
|
|
The ck_pr_inc_zero family of functions return true
|
|
|
|
|
if the result of the increment operation was 0. The functions return
|
|
|
|
|
false otherwise.
