fnmatch - compare a string against a filename wildcard


   @load "fnmatch"

   result = fnmatch(pattern, string, flags)


   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:

          Corresponds to the FNM_CASEFOLD flag as defined in fnmatch(3).

          Corresponds to the FNM_FILE_NAME flag as defined in fnmatch(3).

          Corresponds  to  the  FNM_LEADING_DIR   flag   as   defined   in

          Corresponds to the FNM_NOESCAPE flag as defined in fnmatch(3).

          Corresponds to the FNM_PATHNAME flag as defined in fnmatch(3).

          Corresponds to the FNM_PERIOD flag as defined in fnmatch(3).


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


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