FNMATCH(3)               BSD Library Functions Manual               FNMATCH(3)

NAME
     fnmatch -- test whether a filename or pathname matches a shell-style pat-
     tern

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <fnmatch.h>

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

DESCRIPTION
     The fnmatch() function matches patterns according to the 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
     constants, 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.

     FNM_LEADING_DIR
                   Ignore ``/*'' rest after successful pattern matching.

     FNM_CASEFOLD  Ignore case distinctions in both the pattern and the
                   string.

RETURN VALUES
     The fnmatch() function returns zero if string matches the pattern speci-
     fied by pattern.  It returns the value FNM_NOMATCH if no match is found.
     Otherwise, another non-zero value is returned on error.

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

SEE ALSO
     sh(1), glob(3), regex(3)

STANDARDS
     The current implementation of the fnmatch() function does not conform to
     IEEE Std 1003.2 (``POSIX.2'').  Collating symbol expressions, equivalence
     class expressions and character class expressions are not supported.

HISTORY
     The fnmatch() function first appeared in 4.4BSD.

BUGS
     The pattern `*' matches the empty string, even if FNM_PATHNAME is speci-
     fied.
