[lldb-dev] SBDebugger CreateTarget question

[jingham at apple.com]

Matthew,

You'll know that target creation failed because the SBTarget will be invalid, you just won't know why.  There are a bunch of short-cut methods like this that are convenient to call when you are just poking at the API by hand in the "script" command in lldb, but shouldn't be used if you are writing real programs.  In the long run, we should deprecate the ones of these that are obviously dangerous, and then remove them in the fabled 2.0 version of the lldb API's, though in practice having some "quick and dirty" interfaces is not always bad.

Jim
