ecuutil.c -- utility routines for extended calling unit
Defined functions:
arg_token(parsestr, termchars)
ascii_name_to_hex(name)
ascii_to_hex(ascii)
base_name(fullname)
build_arg_array(cmd, arg, arg_max_quan, narg_rtn)
build_str_array(str, arg, arg_max_quan, narg_rtn)
build_valid_baud_string()
cfree(p, num, size)

disp_termio(ttt, text)
find_shell_chars(command)
get_curr_dir(cdir, cdir_max)
get_home_dir(home_dir)
graphic_char_text(ch, incl_3char)
hex_to_ascii_name(char_val)
make_ecu_subdir()
mem_cpy(dest, src, len)
mkdir_auto(dirfn)
mode_map(mode, mode_str)
pad_zstr_to_len(zstr, len)
perror_errmsg(str)
Rdchk(fd)
skip_ld_break(zstr)
str_classify(sc, str)
str_token(parsestr, termchars)
strerror(err_no)
strip_trail_break(zstr)
yes_or_no(strarg)
Some of these routines are the first coding I did in C
and they just aren't worth improving ... like pad_zstr_to_len().
Don't be too harsh on me.
