glob.h — pathname pattern-matching types

Synopsis

#include <glob.h>

Description

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.
