filter_create_fp(3)

💖 filter_create_fp — a whole manual page, bestie 💖

okay so this is filter_create_fp(3), and it lives in util/filter.h. it's the buffered-stdio glow-up of filter_create_fd, and honestly? she's giving convenient. let's get into it ✨

🌸 NAME 🌸

filter_create_fp — it's literally filter_create_fd, except you get buffered FILE*s instead of raw file descriptors. same energy, softer edges. 🫶

✨ SYNOPSIS ✨

#include <util/filter.h>

NEOERR *filter_create_fp(const char *cmd, FILE **in, FILE **out, FILE **err,
                         pid_t *pid);

that's the whole signature, no cap. 👑

🎀 ARGUMENTS 🎀

• cmd — the sub-command you wanna execute. and listen, she runs it through /bin/sh -c, so it's giving full shell, not just some bare exec. 💅
• in — a pointer where she'll hand you back the stdin pipe. or NULL if you genuinely do not want the stdin pipe, no pressure. 🙈
• out — pointer to return the stdout pipe. NULL if stdout is not your vibe rn.
• err — pointer to return the stderr pipe. NULL if you'd rather not hear it. 😭

ngl, if you pass NULL for one of these, you just don't get that pipe. she's not gonna invent one for you. periodt.

🦋 DESCRIPTION 🦋

so filter_create_fp is identical to filter_create_fd — like, same girl, same brain — except every single one of those pipes is wrapped in a buffered stdio FILE. that's the entire plot twist. buffered. FILE*. slay. 🔥

🌈 RETURN VALUE 🌈

• in — the stdin FILE of the sub process 💜
• out — the stdout FILE of the sub process ⭐
• err — the stderr FILE of the sub process 🍓
• pid — the pid of the sub process 👑
