+ * 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 provide wrapper to the getpwnam or getpwnam_r functions.
