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 bit­
       wise 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 ini­
              tial 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 exten­
       sions.
