FD_CLR(3POSIX)

🌸 FD_CLR — macros for synchronous I/O multiplexing 🌸

okay bestie, this one's from the POSIX Programmer's Manual — it's FD_CLR(3POSIX), and it's literally the tiniest page you've ever seen, but we're gonna treat it with the respect it deserves 💅

📜 PROLOG

This manual page is part of the POSIX Programmer's Manual. Heads up though, bestie: the Linux implementation of this interface may differ (so go peek at the corresponding Linux manual page if you need the tea on Linux behavior), or honestly the interface may not be implemented on Linux at all. Not me being dramatic, that's just what it says. 😭

✨ NAME ✨

FD_CLR — macros for synchronous I/O multiplexing 🦋

🎀 SYNOPSIS 🎀

#include <sys/select.h>

void FD_CLR(int fd, fd_set *fdset);
int FD_ISSET(int fd, fd_set *fdset);
void FD_SET(int fd, fd_set *fdset);
void FD_ZERO(fd_set *fdset);

look at that little family of four, all matching, all iconic 👑
