These comments should indicate which functions they really wrap. An alternative would be to remove the line completely to avoid future copy&paste mistakes. Signed-off-by: Samanta Navarro <ferivoz@riseup.net>

/*
|
||
* According to the Linux-PAM documentation:
|
||
*
|
||
* 4.1. Care about standard library calls
|
||
*
|
||
* In general, writers of authorization-granting applications should
|
||
* assume that each module is likely to call any or all 'libc' functions.
|
||
* For 'libc' functions that return pointers to static/dynamically
|
||
* allocated structures (ie. the library allocates the memory and the
|
||
* user is not expected to 'free()' it) any module call to this function
|
||
* is likely to corrupt a pointer previously obtained by the application.
|
||
* The application programmer should either re-call such a 'libc'
|
||
* function after a call to the Linux-PAM library, or copy the structure
|
||
* contents to some safe area of memory before passing control to the
|
||
* Linux-PAM library.
|
||
*
|
||
* Two important function classes that fall into this category are
|
||
* getpwnam(3) and syslog(3).
|
||
*
|
||
* This file provides wrapper to the getgrgid or getgrgid_r functions.
