an explanation of the string types

[kryton9]

Charles, can you just give an overview of the string types? There are a few and I don't when you are supposed to use them.

[Aurel]

Yeah good point Kent.
zstring -> what is it?
bstring...
etc

 Hi Kent and Aurel,

Null terminated strings:

1 byte characters: zstring asciiz char
2 byte characters: zstring2 wchar (next release)

Bstrings: length encoded & null terminated. Must be freed when finished

1 byte characters: bstring
2 byte characters: bstring2

Dynamic strings. length encoded & null terminated. Automatically freed.
These are the preferred types. The others are for OS calls and other low level stuff.

1 byte characters: string
2 byte characters: wstring

Other string types cstring and gstring are for internal use.

Here is the current list of primitives used by Oxygen. There are a few synonyms in this list

Thanks Charles. Will add that to the reference of if you want just add it, it is useful information.
