glob.h - Man Page

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.

#include <glob.h>

The <glob.h> header shall define the structures and symbolic constants used by the glob() function.

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

The <glob.h> header shall define the size_t type as described in <sys/types.h>.

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.

GLOB_DOOFFS

Specify how many null pointers to add to the beginning of gl_pathv.

GLOB_ERR

Cause glob() to return on error.

GLOB_MARK

Each pathname that is a directory that matches pattern has a <slash> appended.

GLOB_NOCHECK

If pattern does not match any pathname, then return a list consisting of only pattern.

GLOB_NOESCAPE

Disable backslash escaping.

GLOB_NOSORT

Do not sort the pathnames returned.

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.

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 *);

The following sections are informative.
