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.

glob.h — pathname pattern-matching types


#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:

Append generated pathnames to those previously obtained.
Specify how many null pointers to add to the beginning of gl_pathv.
Cause glob() to return on error.
Each pathname that is a directory that matches pattern has a <slash> appended.
If pattern does not match any pathname, then return a list consisting of only pattern.
Disable backslash escaping.
Do not sort the pathnames returned.

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

The scan was stopped because GLOB_ERR was set or (*errfunc)() returned non-zero.
The pattern does not match any existing pathname, and GLOB_NOCHECK was not set in flags.
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.
