-.Dt GLOB 3
-.Os
-.Sh NAME
-.Nm glob ,
-.Nm globfree
-.Nd generate pathnames matching a pattern
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In glob.h
-.Ft int
-.Fn glob "const char *pattern" "int flags" "int (*errfunc)(const char *, int)" "glob_t *pglob"
-.Ft void
-.Fn globfree "glob_t *pglob"
-.Sh DESCRIPTION
-The
-.Fn glob
-function
-is a pathname generator that implements the rules for file name pattern
-matching used by the shell.
-.Pp
-The include file
-.Pa glob.h
-defines the structure type
-.Fa glob_t ,
-which contains at least the following fields:
-.Bd -literal
-typedef struct {
-	int gl_pathc;		/* count of total paths so far */
-	int gl_matchc;		/* count of paths matching pattern */
-	int gl_offs;		/* reserved at beginning of gl_pathv */
-	int gl_flags;		/* returned flags */
-	char **gl_pathv;	/* list of paths matching pattern */
-} glob_t;
-.Ed
-.Pp
-The argument
-.Fa pattern
-is a pointer to a pathname pattern to be expanded.
-The
-.Fn glob
-argument
-matches all accessible pathnames against the pattern and creates
-a list of the pathnames that match.
-In order to have access to a pathname,
-.Fn glob
-requires search permission on every component of a path except the last
-and read permission on each directory of any filename component of
-.Fa pattern
-that contains any of the special characters
-.Ql * ,
-.Ql ?\&
-or
-.Ql \&[ .
-.Pp
-The
-.Fn glob
-argument
-stores the number of matched pathnames into the
-.Fa gl_pathc
-field, and a pointer to a list of pointers to pathnames into the
-.Fa gl_pathv
-field.
-The first pointer after the last pathname is
-.Dv NULL .
-If the pattern does not match any pathnames, the returned number of
-matched paths is set to zero.
-.Pp
-It is the caller's responsibility to create the structure pointed to by
-.Fa pglob .
-The
-.Fn glob
-function allocates other space as needed, including the memory pointed
-to by
-.Fa gl_pathv .
-.Pp
-The argument
-.Fa flags
-is used to modify the behavior of
-.Fn glob .
-The value of
-.Fa flags
-is the bitwise inclusive
-.Tn OR
-of any of the following
-values defined in
-.Pa glob.h :
-.Bl -tag -width GLOB_ALTDIRFUNC
-.It Dv GLOB_APPEND
-Append pathnames generated to the ones from a previous call (or calls)
-to
-.Fn glob .
-The value of
-.Fa gl_pathc
-will be the total matches found by this call and the previous call(s).
-The pathnames are appended to, not merged with the pathnames returned by
-the previous call(s).
-Between calls, the caller must not change the setting of the
-.Dv GLOB_DOOFFS
-flag, nor change the value of
-.Fa gl_offs
-when
-.Dv GLOB_DOOFFS
-is set, nor (obviously) call
-.Fn globfree
-for
-.Fa pglob .
-.It Dv GLOB_DOOFFS
-Make use of the
-.Fa gl_offs
-field.
-If this flag is set,
-.Fa gl_offs
-is used to specify how many
-.Dv NULL
-pointers to prepend to the beginning
-of the
-.Fa gl_pathv
-field.
-In other words,
-.Fa gl_pathv
-will point to
-.Fa gl_offs
-.Dv NULL
-pointers,
-followed by
-.Fa gl_pathc
-pathname pointers, followed by a
-.Dv NULL
-pointer.
-.It Dv GLOB_ERR
-Causes
-.Fn glob
-to return when it encounters a directory that it cannot open or read.
-Ordinarily,
-.Fn glob
-continues to find matches.
-.It Dv GLOB_MARK
-Each pathname that is a directory that matches
-.Fa pattern
-has a slash
-appended.
-.It Dv GLOB_NOCHECK
-If
-.Fa pattern
-does not match any pathname, then
-.Fn glob
-returns a list
-consisting of only
-.Fa pattern ,
-with the number of total pathnames is set to 1, and the number of matched
-pathnames set to 0.
-If
-.Dv GLOB_QUOTE
-is set, its effect is present in the pattern returned.
-.It Dv GLOB_NOSORT
-By default, the pathnames are sorted in ascending
-.Tn ASCII
-order;
-this flag prevents that sorting (speeding up
-.Fn glob ) .
-.El
-.Pp
-The following values may also be included in
-.Fa flags ,
-however, they are non-standard extensions to
-.St -p1003.2 .
-.Bl -tag -width GLOB_ALTDIRFUNC
-.It Dv GLOB_ALTDIRFUNC
-The following additional fields in the pglob structure have been
-initialized with alternate functions for glob to use to open, read,
-and close directories and to get stat information on names found
-in those directories.
-.Bd -literal
-void *(*gl_opendir)(const char * name);
-struct dirent *(*gl_readdir)(void *);
-void (*gl_closedir)(void *);
-int (*gl_lstat)(const char *name, struct stat *st);
-int (*gl_stat)(const char *name, struct stat *st);
-.Ed
-.Pp
-This extension is provided to allow programs such as
-.Xr restore 8
-to provide globbing from directories stored on tape.
-.It Dv GLOB_BRACE
-Pre-process the pattern string to expand
-.Ql {pat,pat,...}
-strings like
-.Xr csh 1 .
-The pattern
-.Ql {}
-is left unexpanded for historical reasons (and
-.Xr csh 1
-does the same thing to
-ease typing
-of
-.Xr find 1
-patterns).
-.It Dv GLOB_MAGCHAR
-Set by the
-.Fn glob
-function if the pattern included globbing characters.
-See the description of the usage of the
-.Fa gl_matchc
-structure member for more details.
-.It Dv GLOB_NOMAGIC
-Is the same as
-.Dv GLOB_NOCHECK
-but it only appends the
-.Fa pattern
-if it does not contain any of the special characters ``*'', ``?'' or ``[''.
-.Dv GLOB_NOMAGIC
-is provided to simplify implementing the historic
-.Xr csh 1
-globbing behavior and should probably not be used anywhere else.
-.It Dv GLOB_QUOTE
-Use the backslash
-.Pq Ql \e
-character for quoting: every occurrence of
-a backslash followed by a character in the pattern is replaced by that
-character, avoiding any special interpretation of the character.
-.It Dv GLOB_TILDE
-Expand patterns that start with
-.Ql ~
-to user name home directories.
-.It Dv GLOB_LIMIT
-Limit the total number of returned pathnames to the value provided in
-.Fa gl_matchc
-(default
-.Dv ARG_MAX ) .
-This option should be set for programs
-that can be coerced into a denial of service attack
-via patterns that expand to a very large number of matches,
-such as a long string of
-.Ql */../*/.. .
-.El
-.Pp
-If, during the search, a directory is encountered that cannot be opened
-or read and
-.Fa errfunc
-is
-.Pf non- Dv NULL ,
-.Fn glob
-calls
-.Fa \*(lp*errfunc\*(rp Ns ( Fa path , errno ) .
-This may be unintuitive: a pattern like
-.Ql */Makefile
-will try to
-.Xr stat 2
-.Ql foo/Makefile
-even if
-.Ql foo
-is not a directory, resulting in a
-call to
-.Fa errfunc .
-The error routine can suppress this action by testing for
-.Er ENOENT
-and
-.Er ENOTDIR ;
-however, the
-.Dv GLOB_ERR
-flag will still cause an immediate
-return when this happens.
-.Pp
-If
-.Fa errfunc
-returns non-zero,
-.Fn glob
-stops the scan and returns
-.Dv GLOB_ABEND
-after setting
-.Fa gl_pathc
-and
-.Fa gl_pathv
-to reflect any paths already matched.
-This also happens if an error is encountered and
-.Dv GLOB_ERR
-is set in
-.Fa flags ,
-regardless of the return value of
-.Fa errfunc ,
-if called.
-If
-.Dv GLOB_ERR
-is not set and either
-.Fa errfunc
-is
-.Dv NULL
-or
-.Fa errfunc
-returns zero, the error is ignored.
-.Pp
-The
-.Fn globfree
-function frees any space associated with
-.Fa pglob
-from a previous call(s) to
-.Fn glob .
-.Sh RETURN VALUES
-On successful completion,
-.Fn glob
-returns zero.
-In addition the fields of
-.Fa pglob
-contain the values described below:
-.Bl -tag -width GLOB_NOCHECK
-.It Fa gl_pathc
-contains the total number of matched pathnames so far.
-This includes other matches from previous invocations of
-.Fn glob
-if
-.Dv GLOB_APPEND
-was specified.
-.It Fa gl_matchc
-contains the number of matched pathnames in the current invocation of
-.Fn glob .
-.It Fa gl_flags
-contains a copy of the
-.Fa flags
-parameter with the bit
-.Dv GLOB_MAGCHAR
-set if
-.Fa pattern
-contained any of the special characters ``*'', ``?'' or ``['', cleared
-if not.
-.It Fa gl_pathv
-contains a pointer to a
-.Dv NULL Ns -terminated
-list of matched pathnames.
-However, if
-.Fa gl_pathc
-is zero, the contents of
-.Fa gl_pathv
-are undefined.
-.El
-.Pp
-If
-.Fn glob
-terminates due to an error, it sets errno and returns one of the
-following non-zero constants, which are defined in the include
-file
-.Aq Pa glob.h :
-.Bl -tag -width GLOB_NOCHECK
-.It Dv GLOB_NOSPACE
-An attempt to allocate memory failed, or if
-.Fa errno
-was 0
-.Dv GLOB_LIMIT
-was specified in the flags and
-.Fa pglob\->gl_matchc
-or more patterns were matched.
-.It Dv GLOB_ABEND
-The scan was stopped because an error was encountered and either
-.Dv GLOB_ERR
-was set or
-.Fa \*(lp*errfunc\*(rp\*(lp\*(rp
-returned non-zero.
-.El
-.Pp
-The arguments
-.Fa pglob\->gl_pathc
-and
-.Fa pglob\->gl_pathv
-are still set as specified above.
-.Sh EXAMPLES
-A rough equivalent of
-.Ql "ls -l *.c *.h"
-can be obtained with the
-following code:
-.Bd -literal -offset indent
-glob_t g;
-
-g.gl_offs = 2;
-glob("*.c", GLOB_DOOFFS, NULL, &g);
-glob("*.h", GLOB_DOOFFS | GLOB_APPEND, NULL, &g);
-g.gl_pathv[0] = "ls";
-g.gl_pathv[1] = "-l";
-execvp("ls", g.gl_pathv);
-.Ed
-.Sh SEE ALSO
-.Xr sh 1 ,
-.Xr fnmatch 3 ,
-.Xr regexp 3
-.Sh STANDARDS
-The
-.Fn glob
-function is expected to be
-.St -p1003.2
-compatible with the exception
-that the flags
-.Dv GLOB_ALTDIRFUNC ,
-.Dv GLOB_BRACE ,
-.Dv GLOB_LIMIT ,
-.Dv GLOB_MAGCHAR ,
-.Dv GLOB_NOMAGIC ,
-.Dv GLOB_QUOTE ,
-and
-.Dv GLOB_TILDE ,
-and the fields
-.Fa gl_matchc
-and
-.Fa gl_flags
-should not be used by applications striving for strict
-.Tn POSIX
-conformance.
-.Sh HISTORY
-The
-.Fn glob
-and
-.Fn globfree
-functions first appeared in
-.Bx 4.4 .
-.Sh BUGS
-Patterns longer than
-.Dv MAXPATHLEN
-may cause unchecked errors.
-.Pp
-The
-.Fn glob
-argument
-may fail and set errno for any of the errors specified for the
-library routines
-.Xr stat 2 ,
-.Xr closedir 3 ,
-.Xr opendir 3 ,
-.Xr readdir 3 ,
-.Xr malloc 3 ,
-and
-.Xr free 3 .
