Thu May 20 13:45:15 1993 Michael Widenius (monty at bitch)
* changed itoa() and ltoa() to use the same interface as microsoft:s
and zortech:s libraryes.
Sun Mar 24 00:30:34 1991 Michael Widenius (monty at LYNX)
* Changed int2str to return BIG converted chars.
Sun Feb 24 00:22:54 1991 Michael Widenius (monty at LYNX)
* Added new function strcend(string,char). Its eqvialent to
if (!(a=strchr(string,char)))
a=strend(string);
Tue Oct 16 18:53:19 1990 Michael Widenius (monty at LYNX)
* Added define BAD_STRING_COMPILER to set define strmov()
if compiler is very bad at stringoperations.
* Changed to use cc on sun-systems instead of gcc.
Sat Sep 29 18:42:31 1990 Michael Widenius (monty at LYNX)
* Added my_atof for sparc system to get some speed.
Sun Mar 11 16:35:59 1990 Monty (monty at monty)
* strnmov() was changed to not fill to-string with null.
* strmake() changed to point at closing null.
Wed Feb 7 20:15:34 1990 David Axmark (davida at isil)
* Made functon strinrstr that is reverse search.
Fri Dec 2 03:37:59 1988 Monty (monty at monty)
* Fixed bug in strcont; It didn't return first found character in
set.

/* memcmp(lhs, rhs, len)

rhs[-]. Note that this is not at all the same as bcmp, which tells

Note: suppose we have int x, y; then memcmp(&x, &y, sizeof x) need
not bear any relation to x-y. This is because byte order is machine
dependent, and also, some machines have integer representations that
are shorter than a machine word and two equal integers might have
different values in the spare bits. On a ones complement machine,
-0 == 0, but the bit patterns are different.

occurs, or NullS if c does not occur in s. This function is called
rindex in V7 and 4.?bsd systems; while not ideal the name is clearer
than strrchr, so rindex remains in strings.h as a macro. NB:
strrchr looks for single characters, not for sets or strings. The
parameter 'c' is declared 'int' so it will go in a register; if your
C compiler is happy with register char change it to that.
