Strtol and strtoul...

[Mark H. Colburn]

I have a question about the wording of the descriptions for the strtol
and strtoul library calls in the ANSI draft standard (I have the October 31,
1988 version): where should endptr point to if an error occurs?

For example, given the following code:
	
		unsigned long	foo;
		char           *ptr;

		foo = strtoul("-12345", &ptr, 0);

where would ptr point to?  The call should return ULONG_MAX with errno
set to ERANGE, but does *ptr = '-' or '\0' (end of string) or is it
indeterminate?  It looks as if it should point to '\0', but...
