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"
