PAM_GETENVLIST(3)      FreeBSD 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
     environment 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.
