/*
|
|
|
|
|
Newsizedstringobject() and newstringobject() try in certain cases
|
|
|
|
|
to share string objects. When the size of the string is zero,
|
|
|
|
|
these routines always return a pointer to the same string object;
|
|
|
|
|
when the size is one, they return a pointer to an already existing
|
|
|
|
|
object if the contents of the string is known. For
|
|
|
|
|
newstringobject() this is always the case, for
|
|
|
|
|
newsizedstringobject() this is the case when the first argument in
|
|
|
|
|
not NULL.
|
|
|
|
|
A common practice to allocate a string and then fill it in or
|
|
|
|
|
change it must be done carefully. It is only allowed to change the
|
|
|
|
|
contents of the string if the obect was gotten from
|
|
|
|
|
newsizedstringobject() with a NULL first argument, because in the
|
|
|
|
|
future these routines may try to do even more sharing of objects.

routine does bounds checking to ensure no overflow, but a better

solution may be to malloc a buffer of appropriate size for each

format. For now, the current solution is sufficient.
