Sometimes you need to create an empty target that will get filled in later. The most common use for this
|
|
is to attach to a process by name or pid where you don't know the executable up front. The most convenient way
|
|
to do this is:
|
|
|
|
target = debugger.CreateTarget('')
|
|
error = lldb.SBError()
|
|
process = target.AttachToProcessWithName(debugger.GetListener(), 'PROCESS_NAME', False, error)
|
|
|
|
or the equivalent arguments for AttachToProcessWithID.
