NAME

       fnmatch - compare a string against a filename wildcard

SYNOPSIS

       @load "fnmatch"

       result = fnmatch(pattern, string, flags)

DESCRIPTION

       The  fnmatch  extension  provides  an  AWK interface to the fnmatch(3) routine.  It adds a
       single function named fnmatch(), one predefined variable (FNM_NOMATCH), and  an  array  of
       flag values named FNM.

       The  first  argument is the filename wildcard to match, the second is the filename string,
       and the third is either zero, or the bitwise OR of one or more of the  flags  in  the  FNM
       array.

       The  return value is zero on success, FNM_NOMATCH if the string did not match the pattern,
       or a different non-zero value if an error occurred.

       The flags are follows:

       FNM["CASEFOLD"]
              Corresponds to the FNM_CASEFOLD flag as defined in fnmatch(3).

       FNM["FILE_NAME"]
              Corresponds to the FNM_FILE_NAME flag as defined in fnmatch(3).

       FNM["LEADING_DIR"]
              Corresponds to the FNM_LEADING_DIR flag as defined in fnmatch(3).

       FNM["NOESCAPE"]
              Corresponds to the FNM_NOESCAPE flag as defined in fnmatch(3).

       FNM["PATHNAME"]
              Corresponds to the FNM_PATHNAME flag as defined in fnmatch(3).

       FNM["PERIOD"]
              Corresponds to the FNM_PERIOD flag as defined in fnmatch(3).

NOTES

       Nothing prevents AWK code from changing the predefined variabale FNM_NOMATCH, but doing so
       may cause strange results.

EXAMPLE

       @load "fnmatch"
       ...
       flags = or(FNM["PERIOD"], FNM["NOESCAPE"])
       if (fnmatch("*.a", "foo.c", flags) == FNM_NOMATCH)
            print "no match"
