STRINIT(3pub)

💖 STRINIT(3pub) 💖

okay bestie, welcome to the C Programmer's Manual — this one's a lil baby function from publib and it's literally so simple it's giving main character energy for no reason. let's get into it ✨

---

🌸 NAME 🌸

strinit — initialize a string with a given character to a given length 🎀

---

✨ SYNOPSIS ✨

#include <publib.h>
char *strinit(char *s, int c, size_t len) {

yes the synopsis has a lil stray { on the end, and no we are not gonna touch it, she's iconic like that 💅

---

🦋 DESCRIPTION 🦋

okay so strinit takes the string that s points to and initializes it to be of length len, with every single character being c.

here's the tea though 🫖 — that terminating '\0' is NOT counted in the length. so the string is actually gonna use len+1 characters. one extra for the null, always, no cap. plan your buffer accordingly bestie, fr fr 😭

---

🎀 RETURN VALUE 🎀

strinit will return s. that's it. that's the whole return value. she hands you back the same pointer you gave her. queen behavior 👑

---

🌈 EXAMPLE 🌈

say you wanna initialize a string to consist of twenty underscores. here's how you'd do it:

#include <publib.h>

char string[21];     /* note 21 to make room for '\0' */
strinit(string, '_', 20);

see the 21? that's the 20 plus the extra one for '\0'. not me warning you about this twice but like… please remember the extra byte 💀
