In the process of coding pam_sql, I was trying to figure out
how pam_get_item and pam_set_item work. From the docs (on kernel.org)
it looks like pam_get_item should either return either a pointer
to my data, or NULL if it couldn't be found. So I should be able
to do something like this:
retval = pam_get_item (pamh, KEY, &data);
if ( ! data ) {
...
}
Alas, when I did this, I wasn't detecting when the data
wasn't found, and my program segfaulted. I ended up doing
this:
retval = pam_get_item (pamh, KEY, &data);
if ( ( retval != PAM_SUCCESS ) || (! data ) ) {
...
}
This *seems* to work, but the docs aren't very clear on this
point. So am I doing it right?
