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 behaviour; 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, for example, with a [] - sequence 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 only implemented 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 non-zero value if there is an error.

CONFORMING TO

       ISO/IEC  9945-2:  1993  (POSIX.2).  The FNM_FILE_NAME, FNM_LEADING_DIR,
       and FNM_CASEFOLD flags are GNU extensions.
