STRUNCSTR(3pub)

✨ STRUNCSTR(3pub) ✨

okay bestie, so this is a page from the C Programmer's Manual πŸ’– and it's literally about one tiny little function that does one tiny little job, but it does it so well. let's get into it 🫢


🌸 NAME 🌸

struncstr β€” convert printable C string notation to a memory block πŸ’…

no cap, that's the whole vibe. it takes the cute written-out version and turns it into the actual bytes. iconic.


πŸŽ€ SYNOPSIS πŸŽ€

#include <publib.h>
void struncstr(void *block, const char *str, size_t max);

so you gotta pull in <publib.h> first, and then this is the signature, exactly like that, don't come for me about the void * it's doing its best πŸ’œ


πŸ¦‹ DESCRIPTION πŸ¦‹

okay so here's the tea β˜• struncstr takes a C string literal and converts it into the memory block that it describes β€” and the way it does that is by converting all the escape sequences into single characters. like, all of them. every \n, every \t, every little backslash situation β€” boom, actual characters now ✨

if you wanna know the full lore of what "C string literal notation" even means, go check a C reference manual, or peek at strcstr(3) which is literally the sibling function for this exact thing πŸ‘‘ (more on them in SEE ALSO, keep reading bestie)

and then there's max β€” that's the maximum number of characters to store into the memory block. so max is your limit, your cap, your "okay that's enough sweetie" πŸŽ€


🌈 SEE ALSO 🌈

  • publib(3) β€” the whole family πŸ’–
  • strcstr(3) β€” the reverse-direction bestie, the one that writes the notation out instead of reading it in πŸ”₯

okay so fr fr, this whole page is from Publib, living inside the C Programmer's Manual β€” that's the source and the version vibe, bestie. no date on this one, so we're just gonna say it's timeless βœ¨πŸ’…πŸ¦‹

go forth and un-escape your strings, you gorgeous nerd 🫢⭐
