Member Typedef Documentation

SharedLibraryDirectoryHelper

using lldb_private::HostInfoBase::SharedLibraryDirectoryHelper = void(FileSpec &this_file)

A helper function for determining the liblldb location.

It receives a FileSpec with the location of file containing this code. It can (optionally) replace it with a file spec pointing to a more canonical copy.
