NAME

pam_getenvlist – returns a list of all the PAM environment variables

CONTENTS

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.
