16 * This file contains a collection of automatically created wrappers
17 * (created by running reentr.pl) for reentrant (thread-safe) versions of
18 * various library calls, such as getpwent_r. The wrapping is done so
19 * that other files like pp_sys.c calling those library functions need not
20 * care about the differences between various platforms' idiosyncrasies
21 * regarding these reentrant interfaces.
