💖 shishi_tkt_postdated_p(3) — the shishi girlies' guide 💖

okay bestie, so this one lives in the shishi manual, section 3 (library calls, the fun ones), and it's called shishi_tkt_postdated_p. yes the _p is for "predicate", she's asking a yes/no question, she's a truth-teller, a main character who only wants to know one thing 🎀

✨ NAME ✨

shishi_tkt_postdated_p — an API function, and yes that's the whole job description, she contains multitudes but mostly she contains a boolean 🌸

✨ SYNOPSIS ✨

#include <shishi.h>

int shishi_tkt_postdated_p(Shishi_tkt * tkt);

like look at her, one include, one call, no drama (okay a little drama, it's Kerberos) 💅

✨ ARGUMENTS ✨

  • Shishi_tkt * tkt — your input variable, the one holding the ticket info. hand her the ticket, she'll do the vibes check on it 🦋

✨ DESCRIPTION ✨

so what we're doing here is determining whether the ticket is postdated. that's it. that's the function. she's a detective and the mystery is one (1) flag 🔍

now let me put you on to what POSTDATED even means, because it's giving lore:

the POSTDATED flag indicates that a ticket has been postdated. the application server can check the authtime field in the ticket to see when the original authentication actually went down — like checking the timestamp on a text to see if they really sent it when they said they did, ngl 📱

some services MAY choose to reject postdated tickets outright (rude but valid), or they may only accept them within a certain period after the original authentication. so there's a window, bestie, and if you miss it, that's on you 🕰️

and here's the important part, the part where you go 😭: when the KDC issues a POSTDATED ticket, it will also be marked as INVALID, so that the application client MUST present the ticket to the KDC to be validated before use.

no cap, that MUST is doing heavy lifting. postdated = not usable yet. you gotta go get it stamped. periodt. 👑

✨ RETURN VALUE ✨

returns non-0 iff the postdated flag is set in the ticket. so: truthy = yes she's postdated, 0 = no she is not, and that's the entire personality 💚

✨ REPORTING BUGS ✨

found a bug? first of all, scream, then report it to <bug-shishi@gnu.org> 📧
