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.

PAM_AUTHENTICATE(3) BSD Library Functions Manual PAM_AUTHENTICATE(3)NAME
pam_authenticate -- perform authentication within the PAM framework
LIBRARY
Pluggable Authentication Module Library (libpam, -lpam)
SYNOPSIS
#include <sys/types.h>
#include <security/pam_appl.h>
int
pam_authenticate(pam_handle_t *pamh, int flags);
DESCRIPTION
The pam_authenticate function attempts to authenticate the user associated with the pam context specified by the pamh argument.
The application is free to call pam_authenticate as many times as it wishes, but some modules may maintain an internal retry counter and
return PAM_MAXTRIES when it exceeds some preset or hardcoded limit.
The flags argument is the binary or of zero or more of the following values:
PAM_SILENT Do not emit any messages.
PAM_DISALLOW_NULL_AUTHTOK
Fail if the user's authentication token is null.
If any other bits are set, pam_authenticate will return PAM_SYMBOL_ERR.
RETURN VALUES
The pam_authenticate function returns one of the following values:
[PAM_ABORT] General failure.
[PAM_AUTHINFO_UNAVAIL]
Authentication information is unavailable.
[PAM_AUTH_ERR] Authentication error.
[PAM_BUF_ERR] Memory buffer error.
[PAM_CONV_ERR] Conversation failure.
[PAM_CRED_INSUFFICIENT]
Insufficient credentials.
[PAM_MAXTRIES] Maximum number of tries exceeded.
[PAM_PERM_DENIED] Permission denied.
[PAM_SERVICE_ERR] Error in service module.
[PAM_SYMBOL_ERR] Invalid symbol.
[PAM_SYSTEM_ERR] System error.
[PAM_USER_UNKNOWN] Unknown user.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.

Hi all...
Well guys and gals, I jumped in at the deep end and found things that PERL cannot do by default.

Well, guys I saw a question about GOTO for Python.
So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).

This is purely a fun project to see if it is possible in PURE... (3 Replies)
