glob.h(7POSIX) POSIX Programmer's Manual glob.h(7POSIX)
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
The <glob.h> header shall define the structures and symbolic constants used by the glob()
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
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>
GLOB_NOCHECK If pattern does not match any pathname, then return a list consisting of
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-
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),
void globfree(glob_t *);
