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.

       FNM_EXTMATCH
	      If this flag (a GNU extension) is	 set,  extended	 patterns  are
	      supported,  as  introduced  by  'ksh' and now supported by other
	      shells.  The extended format is as  follows,  with  pattern-list
	      being a '|' separated list of patterns.

       '?(pattern-list)'
	      The  pattern  matches  if	 zero or one occurrences of any of the
	      patterns in the pattern-list match the input string.

       '*(pattern-list)'
	      The pattern matches if zero or more occurrences of  any  of  the
	      patterns in the pattern-list match the input string.

       '+(pattern-list)'
	      The  pattern  matches  if	 one or more occurrences of any of the
	      patterns in the pattern-list match the input string.

       '@(pattern-list)'
	      The pattern matches if exactly one occurrence of any of the pat-
	      terns in the pattern-list match the input string.

       '!(pattern-list)'
	      The  pattern  matches if the input string cannot be matched with
	      any of the patterns in the pattern-list.

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