Overview

The ck_pr_load(3) family of functions atomically loads the value pointed to by 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.

Return values

This family of functions returns the value contained in the location pointed to by the first argument.
