10 * This file is built by reentr.pl from data in reentr.pl.
12 * "Saruman," I said, standing away from him, "only one hand at a time can
13 * wield the One, and you know that well, so do not trouble to say we!"
15 * This file contains a collection of automatically created wrappers
16 * (created by running reentr.pl) for reentrant (thread-safe) versions of
17 * various library calls, such as getpwent_r. The wrapping is done so
18 * that other files like pp_sys.c calling those library functions need not
19 * care about the differences between various platforms' idiosyncrasies
20 * regarding these reentrant interfaces.
