FNMATCH(3)                 BSD Programmer's Manual                  FNMATCH(3)


     fnmatch - match filename or pathname using shell globbing rules


     #include <fnmatch.h>

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


     The fnmatch() function matches patterns according to the globbing rules
     used by the shell. It checks the string specified by the string argument
     to see if it matches the pattern specified by the pattern argument.

     The flags argument modifies the interpretation of pattern and string. The
     value of flags is the bitwise inclusive OR of any of the following con-
     stants, which are defined in the include file <fnmatch.h>.

     FNM_NOESCAPE  Normally, every occurrence of a backslash ('\') followed by
                   a character in pattern is replaced by that character. This
                   is done to negate any special meaning for the character. If
                   the FNM_NOESCAPE flag is set, a backslash character is
                   treated as an ordinary character.

     FNM_PATHNAME  Slash characters in string must be explicitly matched by
                   slashes in pattern. If this flag is not set, then slashes
                   are treated as regular characters.

     FNM_PERIOD    Leading periods in string must be explicitly matched by
                   periods in pattern. If this flag is not set, then leading
                   periods are treated as regular characters. The definition
                   of "leading" is related to the specification of
                   FNM_PATHNAME. A period is always leading if it is the first
                   character in string. Additionally, if FNM_PATHNAME is set,
                   a period is leading if it immediately follows a slash.

                   Ignore '/*' rest after successful pattern matching.

     FNM_CASEFOLD  Ignore case distinctions in both the pattern and the


     The fnmatch() function returns zero if string matches the pattern speci-
     fied by pattern, otherwise, it returns the value FNM_NOMATCH.

     The fnmatch() function conforms to IEEE Std 1003.2-1992 ("POSIX.2") and
     X/Open Portability Guide Issue 4, Version 2 ("XPG4.2").

     Note, however, that the flags FNM_LEADING_DIR and FNM_CASEFOLD are exten-
     sions and should not be used by applications striving for strict stan-
     dards conformance.


     The fnmatch() function first appeared in 4.4BSD.
