Trf_TransformBuffer(3)

💖 Trf_TransformBuffer — the manual page, but make it cute 💖

okay bestie, so this is a page from Library Functions Manual for Trf_TransformBuffer(3), and honestly? it's giving "the fast one". let's get into it 🦋

✨ NAME ✨

Trf_TransformBuffer — your lil interface to procedures that transform character sequences. that's the whole vibe. no cap. 💅

🌸 SYNOPSIS 🌸

#include <transform.h>

int Trf_TransformBuffer
(
     Trf_ControlBlock ctrlBlock,
     unsigned char *buf,
     int bufLen,
     Tcl_Interp *interp,
     ClientData clientData
);

look at her. five arguments. she's a main character and she knows it. 👑

🎀 PARAMETERS 🎀

here's the breakdown, bestie, every single one, no skipping:

• Trf_ControlBlock ctrlBlock — the state of your encoder/decoder. like, where it's at emotionally. the whole situation. 💜
• unsigned char *buf — the characters you want to transform. the actual content. the material. ✨
• int bufLen — how many characters. the count. the numbers. 🔢
• Tcl_Interp *interp — the interpreter used for error messages, and yes it can be NULL (she's allowed to ghost). 💀
• ClientData clientData — arbitrary information, as defined in Trf_TypeDefinition.clientData. literally whatever you want to stash there. go off. 🙈

🌈 DESCRIPTION 🌈

so a procedure of this type gets called to encode/decode a complete buffer. that's the assignment. that's what she does. 🫶

the return value is a standard tcl error code. (iykyk.)

now listen, if it fails and interp is not NULL, you should leave an error message in the result area of that specified interpreter. don't just silently flop, bestie, tell the interpreter what went wrong. 😭

⚠️ important bit: only one of Trf_TransformCharacter and Trf_TransformBuffer must be provided. pick one. not both. this is not a both situation.

and here's the tea: the first named one (Trf_TransformCharacter) is easier to implement, but this one (Trf_TransformBuffer) should be faster. speed vs. effort, the eternal struggle. 💅

and if you do provide both? okay diva, then Trf_TransformBuffer takes precedence. she wins. periodt. 👑
