💖 fnmatch.h(0P) — the POSIX Programmer's Manual page, bestie edition 🎀

okay so this is fnmatch.h(0P), living in the POSIX Programmer's Manual, and we're about to make it make sense. 🦋

✨ PROLOG ✨

so like, heads up: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (so go consult the corresponding Linux manual page for the deets on Linux behavior), or honestly the interface may not even be implemented on Linux at all. 🙈 vibe check accordingly.

🌸 NAME 🌸

fnmatch.h — filename-matching types. it's giving "the header that holds the pattern-matching constants." ✨

🎀 SYNOPSIS 🎀

#include <fnmatch.h>

that's it, that's the whole synopsis, she's simple, she's iconic. 💅

💜 DESCRIPTION 💜

so the <fnmatch.h> header shall define the following symbolic constants, and they are lowkey the whole point of this file:

  • FNM_NOMATCH — the string does not match the specified pattern. 💀 (yeah, it's the "no match" flag, she's the heartbreak constant)
  • FNM_PATHNAME — a <slash> in the string only matches a <slash> in the pattern. no cheating, slashes stay in their lane. 🔥
  • FNM_PERIOD — a leading <period> in the string must be exactly matched by a <period> in the pattern. periodt. no wildcard sneaking in front of a dot. ✨
  • FNM_NOESCAPE — disable backslash escaping. turn the escape hatch off, bestie. 🚪

then, the following shall be declared as a function and may also be defined as a macro. and a function prototype shall be provided:

int fnmatch(const char *, const char *, int);

yup, three args, int return, we move. 👑

the following sections are informative — so like, cute bonus reading, not the binding law of the land. 📚

🌈 APPLICATION USAGE 🌈

None. (literally nothing, she said "no notes." 🫶)

🧚 RATIONALE 🧚

None. (again, no notes, we stan a low-maintenance section. 😭)

⭐ FUTURE DIRECTIONS ⭐

None. (she's not going anywhere, she's staying exactly like this. 💅)
