33 * 4.1. Care about standard library calls
35 * In general, writers of authorization-granting applications should
36 * assume that each module is likely to call any or all 'libc' functions.
37 * For 'libc' functions that return pointers to static/dynamically
38 * allocated structures (ie. the library allocates the memory and the
39 * user is not expected to 'free()' it) any module call to this function
40 * is likely to corrupt a pointer previously obtained by the application.
41 * The application programmer should either re-call such a 'libc'
42 * function after a call to the Linux-PAM library, or copy the structure
43 * contents to some safe area of memory before passing control to the
46 * Two important function classes that fall into this category are
47 * getpwnam(3) and syslog(3).
49 * This file provide wrapper to the getpwnam or getpwnam_r functions.
