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.
