glob.h(0P)

glob.h — pathname pattern-matching types 💅✨

okay bestie, so this page is from the POSIX Programmer's Manual (that's the glob.h(0P) joint right there in the corner 👑). Real talk though: the Linux implementation of this interface may differ — so if you're on Linux, go peek at the corresponding Linux manual page for the actual deets — or honestly the interface might not even be implemented on Linux at all. 🙈

🌸 PROLOG 🌸

This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

🎀 NAME 🎀

glob.h — pathname pattern-matching types. that's it, that's the name, iconic.

---

✨ SYNOPSIS ✨

#include <glob.h>

---

💖 DESCRIPTION 💖

So the <glob.h> header shall define the structures and symbolic constants that the glob() function uses. it's giving "support system for the main character" fr fr.

The <glob.h> header shall define the glob_t structure type, which shall include at least these members:

size_t   gl_pathc Count of paths matched by pattern.
char   **gl_pathv Pointer to a list of matched pathnames.
size_t   gl_offs  Slots to reserve at the beginning of gl_pathv.

• gl_pathc — count of paths matched by pattern. the headcount bestie 💀
• gl_pathv — pointer to a list of matched pathnames. the actual roster ✨
• gl_offs — slots to reserve at the beginning of gl_pathv. like saving seats at the front of the row 🫶

The <glob.h> header shall define the size_t type as described in <sys/types.h>. yes, that <sys/types.h>, the one you already know and love 💜

The <glob.h> header shall define the following symbolic constants as values for the flags argument:

• GLOB_APPEND — append generated pathnames to those previously obtained. not me just adding to the pile 🎀
• GLOB_DOOFFS — specify how many null pointers to add to the beginning of gl_pathv. blank slots at the start, periodt.
• GLOB_ERR — cause glob() to return on error. no patience, we're leaving 🏃‍♀️
• GLOB_MARK — each pathname that is a directory that matches pattern has a <slash> appended. directory girls get a little accessory 💅
• GLOB_NOCHECK — if pattern does not match any pathname, then return a list consisting of only pattern. if nobody shows up, at least you showed up for yourself 😭
• GLOB_NOESCAPE — disable backslash escaping. backslash, you are OFF the team.
• GLOB_NOSORT — do not sort the pathnames returned. chaotic order, we don't gatekeep 🦋

The <glob.h> header shall define the following symbolic constants as error return values:

• GLOB_ABORTED — the scan was stopped because GLOB_ERR was set or (*errfunc)() returned non-zero.
• GLOB_NOMATCH — the pattern does not match any existing pathname, and GLOB_NOCHECK was not set in flags.
• GLOB_NOSPACE — an attempt to allocate memory failed. bestie ran out of room, it happens 😭

The following shall be declared as functions and may also be defined as macros. Function prototypes shall be provided.

int  glob(const char *restrict, int, int(*)(const char *, int),
         glob_t *restrict);
void globfree(glob_t *);
