<A REL=DEFINITION HREF="#pathname-match-p"><B>pathname-match-p</B></A> returns true if <I>pathname</I> matches <I>wildcard</I>, otherwise <A REL=DEFINITION HREF="a_nil.htm#nil"><B>nil</B></A>. The matching rules are <A REL=DEFINITION HREF="26_glo_i.htm#implementation-defined"><I>implementation-defined</I></A> but should be consistent with <A REL=DEFINITION HREF="f_dir.htm#directory"><B>directory</B></A>.

It is valid for <I>pathname</I> to be a wild <A REL=DEFINITION HREF="26_glo_p.htm#pathname"><I>pathname</I></A>; a wildcard field in <I>pathname</I> only matches a wildcard field in <I>wildcard</I> (i.e., <A REL=DEFINITION HREF="#pathname-match-p"><B>pathname-match-p</B></A> is not commutative). It is valid for <I>wildcard</I> to be a non-wild <A REL=DEFINITION HREF="26_glo_p.htm#pathname"><I>pathname</I></A>. <P>
