+ * 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.
