/* ??? This interface isn't intended to be specific to any particular kind
|
|
of remote (hardware, simulator, whatever). However, at the present
|
|
time it is only used by the simulators. At some point this should be
|
|
an entity onto itself. For example, it's wrong that the definitions of the
|
|
functions host_to_target_errno, target_to_host_open live in the simulator
|
|
sources. It would also be wrong for such functions to live in gdb
|
|
sources. Until such time perhaps it would be best to avoid adding
|
|
prototypes of functions (and thus expanding the definition of the

interface). */
