### NAME

pam_getenvlist - returns a list of all the PAM environment variables

### LIBRARY

### SYNOPSIS

```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.
