gsasl_base64_decode(3)

📦 version 1.10.0, in ubuntu jammy

💖 gsasl_base64_decode — the gsasl manual, bestie edition 💖

okay so you're looking at a page from the gsasl manual, and honestly? this one is a little retro, a little deprecated, but we're gonna give it the respect it deserves. sit down, grab a strawberry 🍓, and let's decode some Base64 together.

✨ NAME ✨

gsasl_base64_decode — it's an API function, bestie. that's the whole name. no cap.

🌸 SYNOPSIS 🌸

#include <gsasl.h>

int gsasl_base64_decode(char const * src, char * target, size_t
targsize);

there she is. one function, three args, very demure, very mindful. 🎀

🦋 ARGUMENTS 🦋

  • char const * src — the input byte array. this is the stuff you're feeding in, and no, you don't get to touch it, it's const for a reason. 💅
  • char * target — the output byte array. this is where the decoded goodies land. 🫶
  • size_t targsize — the size of that output byte array. know your limits, queen. 👑

💜 DESCRIPTION 💜

so what does it do? it decodes Base64 data. that's it, that's the vibe. ✨

the way it works: it skips all whitespace anywhere — every space, every newline, every lil invisible gremlin character, gone, ignored, not invited to the party. 🙈 then it converts characters, four at a time, starting at (or after) src, turning those Base64 numbers into three 8 bit bytes in the target area. four in, three out. math is math. 🌈

Return value: it hands you back the number of data bytes stored at the target, or -1 on error. so like, if you get -1, something went wrong and you should probably look at it. 😭

💀 DEPRECATED 💀

bestie. listen. this one is deprecated. i'm not being dramatic, the manpage says so.

Use gsasl_base64_from() instead. that's the glow-up version. this function still exists, but it's giving "we don't really do this anymore." use the new one, i'm begging. 🧚
