💖 Trf_WriteProc — the manual page, but make it make sense ✨

okay so this is Trf_WriteProc(3) from the Library Functions Manual, and bestie, it's literally the interface to the procedures an encoder/decoder uses to write out its transformation results. it's giving "callback energy" and we're obsessed 🫶

🌸 NAME 🌸

Trf_WriteProc — interface to procedures used by an encoder/decoder to write its transformation results. 🦋

✨ SYNOPSIS ✨

#include <transform.h>

int Trf_WriteProc
(
     ClientData clientData,
     unsigned char *outString,
     int outLen,
     Tcl_Interp *interp
);

like yes, four arguments, she's a whole function signature, periodt 💅

🎀 PARAMETERS 🎀

  • ClientData clientData — arbitrary information, defined back whenever the controlblock was created. it's just vibes you carry around, no cap.
  • unsigned char *outString — the buffer holding the characters to write. that's the goods, the payload, the moment 💖
  • int outLen — how many characters are actually in that buffer. count them, don't guess, fr fr.
  • Tcl_Interp *interp — the interpreter used for error messages, and yep, NULL is possible here. so check before you touch, bestie 😭

🌈 DESCRIPTION 🌈

so here's the tea: procedures of this type get called by an encoder/decoder to write out (partial) transformation results. the whole point is decoupling — the final destination of the data is separated from the generation of that data. it's giving "don't worry about where it's going, just make it" 🧚

the return value is a standard tcl error code, okay? that's the vibe check right there.

in case of failure, and if interp is not NULL, you should leave an error message in the result area of the specified interpreter. do not skip this step, it's not optional, and nobody wants a mystery failure with no message 💀

👑 SEE ALSO 👑

and that's the whole page, bestie, you ate it up 💅✨

cute little sign-off: this one was generated by c2man from transform.h, dated 27 August 2002. iconic. historic. a true main character moment 👑🌸
