| my_strtoul - parse a integer in a string |
*------------------------------------------*
This routine is my private implementation of the standard ANSII library routine strtoul().
It taks a pointer to a string which is assumed to be pointing at some digits and returns
the resulting integer. The pointer to the character that stopped the scan is returned
in endptr.
This routine is coded here for the following reasons:
(1). strtoul() is a ANSI standard routine which another installation might not have
if they don't have a full ANSI runtime library.
(2). I don't need all the generality of strtoul(). The base is always assumed as 10
here and endptr is never NULL.
(3). There is a bug in the Mac MPW strtoul() routine! Ah-ha, the REAL reason! It
seems that MPW's strtoul() treats characters as signed. We could have characters
with values larger than 127 in our strings. This causes MPW's strtoul() to
fail in wierd ways (like when it passes such charas to isalnum()).

| CMAddMsgInserts - add all inserts to an error message |
*-------------------------------------------------------*
This routine takes the (error) message string in msgString and replaces all substrings
of the form "^n" with the inserts from the variable arg list of insert strings. The
function returns the edited msgString as its result.
The string buffer must be passed in msgString. Its max length is also specified but this
must be a value less than or equal 1024 (not including delimiting null). The message will
be truncated to fit in the buffer. The string pointer is returned as the function
result.
The substring "^0" is replaced with the first insert. "^1" is replaced with the second
insert, and so on. It is assumed that there are enough insert strings to cover all the
"^n"s called for (not unlike printf()).
Note, the "^n"s in the message string do not have to be in ascending order. Thus "^1"
could occur before "^0" in the msgString.

| CMReturnContainerName - get container identification |
*------------------------------------------------------*
Generally the errors reported are provided with at least one insert that identifies which
container we're talking about. The wording of the messages defined for the Container
Manager assume this identification insert. The identification takes the form of the
container "name" which is obtained from a handler routine provided for that purpose.
For convenience, the name providing handler routine is allowed to be optional, i.e., the
user need not provide one. This means every time we want to get the identification we
must test to see if the handler was provided. This could be a waste of code space,
particularly since we mostly use this for error reporting ("mostly" -- actually this is
the only context it is presenting used in).
To avoid the space waste, this routine is provided to do the test and call the handler if
it exists. If it doesn't exist the container type name (using the TYPENAMEx macro) is
used. If it does, we use the handler.
Note, this routine is available to users (usually handler writers) so that they too can
generalize their error reporting/message routines and word their messages with the
container identification.
