How to get sub string?

[Paul Hsieh]

In the C API you would do this as follows:

bstring orgstr, newstr;
...
bassignmidstr (newstr=bfromcstr(""), orgstr, start, length);

Or, if you just need a reference:

bstring orgstr;
struct tagbstring newrstr;
...
bmid2tbstr (newrstr, orgstr, start, length);

In the C++ API you would do this as follows:

CBstring orgstr;
struct tagbstring tmp;
...
bmid2tbstr (tmp, orgstr, start, length);
CBString newstr(tmp);
