Trf_TransformCharacter(3)

📦 version 2.1.4-dfsg3, in debian bookworm, debian trixie, ubuntu jammy, ubuntu noble, ubuntu questing, ubuntu resolute, ubuntu stonking

✨ NAME ✨

ok so Trf_TransformCharacter — it's the interface to procedures that transform one single character. literally just one. one lil guy. that's the whole job bestie 💖

this one lives in the Library Functions Manual (section 3), so you already know it's a C library thing, not a command you type in your shell 🫶

🌸 SYNOPSIS 🌸

#include <transform.h>

int Trf_TransformCharacter
(
     Trf_ControlBlock ctrlBlock,
     unsigned int character,
     Tcl_Interp *interp,
     ClientData clientData
);

🎀 PARAMETERS 🎀

  • Trf_ControlBlock ctrlBlock — the state of the encoder/decoder. it's giving "vibe holder" for whatever your transform is in the middle of doing 💅
  • unsigned int character — the character you're about to transform. yes, THE character. the one. the main character, if you will 👑
  • Tcl_Interp *interp — the interpreter for error messages, and heads up, NULL is possible here. so like, don't just assume it's there, bestie 🙈
  • ClientData clientData — arbitrary information, exactly as defined in Trf_TypeDefinition.clientData. whatever you stuffed in there, it comes back to you here 🎁

🦋 DESCRIPTION 🦋

so a procedure of this type gets called to encode/decode a single character ✨ that's it, that's the moment.

the return value is a standard tcl error code. no cap.

if it fails and interp isn't NULL, you should leave an error message sitting in the result area of that specified interpreter. like, tell them what went wrong, don't just ghost them 😭

⚠️ real talk: you must provide only one of Trf_TransformCharacter and Trf_TransformBuffer. pick one, not both, periodt.

which one tho? here's the tea:

  • this one (Trf_TransformCharacter) is easier to implement — lowkey the cozy option 🧸
  • Trf_TransformBuffer should be faster — the highkey glow-up option 🔥

and if you're chaotic and provide both? then Trf_TransformBuffer takes precedence. it just does. it's the main character in that scenario 💀

ok that's the whole page bestie, you ate that 💖 this was generated by c2man from transform.h, dated 27 August 2002 (yeah, vintage, iconic, we love a classic 🎀), and it's the man page for Trf_TransformCharacter(3). go forth and transform exactly one character at a time, no more, no less 🌈⭐💅
