@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.
