cgi_url_validate(3)

💖 cgi_url_validate — the "is this link even allowed bestie" check 💖

okay so picture this: it's cgi_url_validate(3) from the cgi/cgi.h crew, and it's here to do exactly one job and do it adorably. no cap. 🦋

✨ NAME ✨

cgi_url_validate — validate that url is of an allowed format 👑

🌸 SYNOPSIS 🌸

#include <cgi/cgi.h>

NEOERR *cgi_url_validate (const char *buf, char **esc);

🎀 ARGUMENTS 🎀

• buf — a 0 terminated string, periodt. that's the whole vibe. 💅

💜 DESCRIPTION 💜

so cgi_url_validate is gonna peek at your URL and check that it starts with one of the accepted safe schemes. that's it, that's the assignment. ✨

if it does not start with one of those, bestie, it hands you back "#" as a safe substitute — like, a lil placeholder so nothing sketchy sneaks through. 🫶

the currently accepted schemes are http, https, ftp and mailto. iconic lineup honestly. 🌈

then — and this is the part that matters — it html escapes the entire URL so that it's safe to insert in an href attribute. yes ma'am, all of it. every character gets the treatment. 🔥

⭐ RETURN VALUE ⭐

• esc — a newly allocated string 💖
