PAM_GETENVLIST(3)	 BSD Library Functions Manual	     PAM_GETENVLIST(3)

NAME
     pam_getenvlist -- returns a list of all the PAM environment variables

LIBRARY
     Pluggable Authentication Module Library (libpam, -lpam)

SYNOPSIS
     #include <sys/types.h>
     #include <security/pam_appl.h>

     char **
     pam_getenvlist(pam_handle_t *pamh);

DESCRIPTION
     The pam_getenvlist	function returns a copy	of the given PAM context's en-
     vironment list as a pointer to an array of	strings.  The last element in
     the array is NULL.	 The pointer is	suitable for assignment	to environ.

     The array and the strings it lists	are allocated using malloc(3), and
     should be released	using free(3) after use:

	 char **envlist, **env;

	 envlist = environ;
	 environ = pam_getenvlist(pamh);
	 /* do something nifty */
	 for (env = environ; *env != NULL; env++)
	     free(*env);
	 free(environ);
	 environ = envlist;

RETURN VALUES
     The pam_getenvlist	function returns NULL on failure.
