NAME

       fnmatch - match filename or pathname

SYNOPSIS

       #include <fnmatch.h>

       int fnmatch(const char *pattern, const char *string, int flags);

DESCRIPTION

       The  fnmatch()  function  checks whether the string argument matches the pattern argument,
       which is a shell wildcard pattern.

       The flags argument modifies the behavior; it is the bitwise OR of  zero  or  more  of  the
       following flags:

       FNM_NOESCAPE
              If this flag is set, treat backslash as an ordinary character, instead of an escape
              character.

       FNM_PATHNAME
              If this flag is set, match a slash in string only with a slash in pattern  and  not
              by  an  asterisk  (*)  or  a  question  mark  (?)  metacharacter,  nor by a bracket
              expression ([]) containing a slash.

       FNM_PERIOD
              If this flag is set, a leading period in string has to  be  matched  exactly  by  a
              period  in  pattern.   A  period  is  considered  to  be leading if it is the first
              character in string, or if both FNM_PATHNAME is  set  and  the  period  immediately
              follows a slash.

       FNM_FILE_NAME
              This is a GNU synonym for FNM_PATHNAME.

       FNM_LEADING_DIR
              If  this  flag (a GNU extension) is set, the pattern is considered to be matched if
              it matches an initial segment of string which is followed by a slash.  This flag is
              mainly for the internal use of glibc and is implemented only in certain cases.

       FNM_CASEFOLD
              If this flag (a GNU extension) is set, the pattern is matched case-insensitively.

RETURN VALUE

       Zero  if string matches pattern, FNM_NOMATCH if there is no match or another nonzero value
       if there is an error.

CONFORMING TO

       POSIX.2.  The FNM_FILE_NAME, FNM_LEADING_DIR, and FNM_CASEFOLD flags are GNU extensions.
