STRRTRIM(3pub)

okay so bestie, welcome to the STRRTRIM(3pub) page from the C Programmer's Manual 💖 this one is short and sweet and it's giving "tiny utility, big helper energy." Let's go.

🌸 NAME 🌸

strrtrim — remove trailing whitespace. That's it. That's the whole job. She trims the right side. Slay.

🎀 SYNOPSIS 🎀

#include <publib.h>
char *strrtrim(char *s);

💅 DESCRIPTION 💅

strrtrim removes all trailing whitespace characters from the end of a string. As whitespace is counted everything for which isspace(3) returns true.

So like, it goes to the end of your string and starts deleting whitespace until there's no more trailing whitespace left. And what counts as whitespace? Everything that makes isspace(3) say "true." No cap. 🧚

✨ RETURN VALUE ✨

strltrim returns its argument.

Bestie, yes, the page literally says strltrim here, not strrtrim. I am not fixing it, I am just preserving the lore. 💀

🦋 EXAMPLE 🦋

To remove whitespace from the end of all lines, you might do the following:

#include <publib.h>

int main(void) {
     char line[512];

     while (fgets(line, sizeof(line), stdio) != NULL) {
          strrtrim(line);
          printf("%s", line);
     }
     return 0;
}

And yes, the example literally uses stdio in the fgets call. That's what the page says, so that's what I'm giving you. Copy it exactly, bestie. 😭
