45 | # After the prototypes one can have |X=...|Y=... to define more types. | |

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