18
|
|
|
|
|
|
* (created by running reentr.pl) for reentrant (thread-safe) versions of |
19
|
|
|
|
|
|
* various library calls, such as getpwent_r. The wrapping is done so |
20
|
|
|
|
|
|
* that other files like pp_sys.c calling those library functions need not |
21
|
|
|
|
|
|
* care about the differences between various platforms' idiosyncrasies |
22
|
|
|
|
|
|
