1 @deftypefn Replacement int fnmatch (const char *@var{pattern}, const char *@var{string}, int @var{flags})
|
|
|
2
|
|
|
3 Matches @var{string} against @var{pattern}, returning zero if it
|
|
|
4 matches, @code{FNM_NOMATCH} if not. @var{pattern} may contain the
|
|
|
5 wildcards @code{?} to match any one character, @code{*} to match any
|
|
|
6 zero or more characters, or a set of alternate characters in square
|
|
|
7 brackets, like @samp{[a-gt8]}, which match one character (@code{a}
|
|
|
8 through @code{g}, or @code{t}, or @code{8}, in this example) if that one
|
|
|
9 character is in the set. A set may be inverted (i.e., match anything
|
|
|
10 except what's in the set) by giving @code{^} or @code{!} as the first
|
|
|
11 character in the set. To include those characters in the set, list them
|
|
|
12 as anything other than the first character of the set. To include a
|
|
|
13 dash in the set, list it last in the set. A backslash character makes
|
|
|
14 the following character not special, so for example you could match
|
|
|
15 against a literal asterisk with @samp{\*}. To match a literal
|
|
|
16 backslash, use @samp{\\}.
|
|
|
17
|
|
|
18 @code{flags} controls various aspects of the matching process, and is a
|
|
|
19 boolean OR of zero or more of the following values (defined in
|
|
|
20 @code{<fnmatch.h>}):
|
|
|
21
|
|
|
22 @table @code
|
|
|
23
|
|
|
24 @item FNM_PATHNAME
|
|
|
25 @itemx FNM_FILE_NAME
|
|
|
26 @var{string} is assumed to be a path name. No wildcard will ever match
|
|
|
27 @code{/}.
|
|
|
28
|
|
|
29 @item FNM_NOESCAPE
|
|
|
30 Do not interpret backslashes as quoting the following special character.
|
|
|
31
|
|
|
32 @item FNM_PERIOD
|
|
|
33 A leading period (at the beginning of @var{string}, or if
|
|
|
34 @code{FNM_PATHNAME} after a slash) is not matched by @code{*} or
|
|
|
35 @code{?} but must be matched explicitly.
|
|
|
36
|
|
|
37 @item FNM_LEADING_DIR
|
|
|
38 Means that @var{string} also matches @var{pattern} if some initial part
|
|
|
39 of @var{string} matches, and is followed by @code{/} and zero or more
|
|
|
40 characters. For example, @samp{foo*} would match either @samp{foobar}
|
|
|
41 or @samp{foobar/grill}.
|
|
|
42
|
|
|
43 @item FNM_CASEFOLD
|
|
|
44 Ignores case when performing the comparison.
