VS_Error_GetFields VS_Error_GetFields retrieves information associated
with an error handle. An error handle is used to pass error
information to and from VolServ.
An error handle is associated with each command handle and
with each notify handle. There is also a global error handle for
errors that cannot be associated with a command.
After a VolServ request or an attempt to receive callbacks fails,
information is stored in an error handle.
VS_Error_GetFields allows the user to retrieve this
information.
