@deftypefn Replacement int fnmatch (const char *@var{pattern}, const char *@var{string}, int @var{flags})
|
|
|
|
Matches @var{string} against @var{pattern}, returning zero if it
|
|
matches, @code{FNM_NOMATCH} if not. @var{pattern} may contain the
|
|
wildcards @code{?} to match any one character, @code{*} to match any
|
|
zero or more characters, or a set of alternate characters in square
|
|
brackets, like @samp{[a-gt8]}, which match one character (@code{a}
|
|
through @code{g}, or @code{t}, or @code{8}, in this example) if that one
|
|
character is in the set. A set may be inverted (i.e. match anything
|
|
except what's in the set) by giving @code{^} or @code{!} as the first
|
|
character in the set. To include those characters in the set, list them
|
|
as anything other than the first character of the set. To include a
|
|
dash in the set, list it last in the set. A backslash character makes
|
|
the following character not special, so for example you could match
|
|
against a literal asterisk with @samp{\*}. To match a literal
|
|
backslash, use @samp{\\}.
|
|
|
|
@code{flags} controls various aspects of the matching process, and is a
|
|
boolean OR of zero or more of the following values (defined in
|
|
@code{<fnmatch.h>}:
|
|
|
|
@table @code
|
|
|
|
@item FNM_PATHNAME
|
|
@itemx FNM_FILE_NAME
|
|
@var{string} is assumed to be a path name. No wildcard will ever match
|
|
@code{/}.
|
|
|
|
@item FNM_NOESCAPE
|
|
Do not interpret backslashes as quoting the following special character.
|
|
|
|
@item FNM_PERIOD
|
|
A leading period (at the beginning of @var{string}, or if
|
|
@code{FNM_PATHNAME} after a slash) is not matched by @code{*} or
|
|
@code{?} but must be matched explicitly.
|
|
|
|
@item FNM_LEADING_DIR
|
|
Means that @var{string} also matches @var{pattern} if some initial part
|
|
of @var{string} matches, and is followed by @code{/} and zero or more
|
|
characters. For example, @samp{foo*} would match either @samp{foobar}
|
|
or @samp{foobar/grill}.
|
|
|
|
@item FNM_CASEFOLD
|
|
Ignores case when performing the comparison.
