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
     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.
