PAM_GETENVLIST(3)       NetBSD 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.
