FNMATCH(3am)               GNU Awk Extension Modules              FNMATCH(3am)




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) rou-
       tine.  It adds a single function named fnmatch(3), one predefined  vari-
       able (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 fnmatch(3).

       FNM["FILE_NAME"]
              Corresponds  to the fnmatch(3).

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

       FNM["NOESCAPE"]
              Corresponds to the fnmatch(3).

       FNM["PATHNAME"]
              Corresponds to the fnmatch(3).

       FNM["PERIOD"]
              Corresponds to the 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"
