✨ sysdecode_utrace(3) ✨

okay so bestie, this is the sysdecode_utrace(3) manual page β€” the one that’s all about turning a utrace record into a text description. it’s giving β€œtranslator for tiny trace receipts,” and honestly? iconic. πŸ’…


πŸ’– NAME πŸ’–

sysdecode_utrace β€” produce text description of a utrace record

πŸ“š LIBRARY πŸ“š

library β€œlibsysdecode”

πŸ› οΈ SYNOPSIS πŸ› οΈ

#include <sysdecode.h>

int
sysdecode_utrace(FILE *fp, void *buf, size_t len, int decimal);

🌸 DESCRIPTION 🌸

okay so sysdecode_utrace() takes a utrace(2) record β€” identified by buf and len β€” and outputs a textual representation of it to the output stream fp. cute, right? it’s literally handing your trace record a little text outfit. πŸŽ€

but here’s the vibe check: this function only outputs a representation for <em>certain types</em> of records. it’s not out here describing every single thing. πŸ™ˆ

  • if a record is recognized, the function outputs the description and returns a non-zero value. slay. ✨
  • if the record is not recognized, the function does not output anything and returns zero. no output, no drama. πŸ’€

and which records is it currently recognizing? the page says sysdecode_utrace() currently recognizes utrace(2) records generated by malloc(3) and rtld(1). so those two are in the group chat. 🫢

πŸ” RETURN VALUES πŸ”

sysdecode_utrace() returns a non-zero value if it recognizes a utrace(2) record; otherwise it returns zero. that’s the whole yes/no situation, and the function said what it said. periodt. πŸ‘‘
