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 ele-
     ment 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.

PAM_GET_USER(3) 					   BSD Library Functions Manual 					   PAM_GET_USER(3)

NAME

     pam_get_user -- retrieve user name

LIBRARY

     Pluggable Authentication Module Library (libpam, -lpam)

SYNOPSIS

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

     int
     pam_get_user(pam_handle_t *pamh, const char **user, const char *prompt);

DESCRIPTION

     The pam_get_user() function returns the name of the target user, as specified to pam_start(3).  If no user was specified, nor set using
     pam_set_item(3), pam_get_user() will prompt for a user name.  Either way, a pointer to the user name is stored in the location pointed to by
     the user argument, and the corresponding PAM item is updated.

     The prompt argument specifies a prompt to use if no user name is cached.  If it is NULL, the PAM_USER_PROMPT item will be used.  If that item
     is also NULL, a hardcoded default prompt will be used.  Additionally, when pam_get_user() is called from a service module, the prompt may be
     affected by module options as described below.  The prompt is then expanded using openpam_subst(3) before it is passed to the conversation
     function.

MODULE OPTIONS

     When called by a service module, pam_get_user() will recognize the following module options:

     user_prompt	 Prompt to use when asking for the user name.  This option overrides both the prompt argument and the PAM_USER_PROMPT
			 item.

RETURN VALUES

     The pam_get_user() function returns one of the following values:

     [PAM_BUF_ERR]	 Memory buffer error.

     [PAM_CONV_ERR]	 Conversation failure.

     [PAM_SYSTEM_ERR]	 System error.
