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 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 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.
