14 /// @class HostInfo HostInfo.h "lldb/Host/HostInfo.h"
15 /// A class that provides host computer information.
17 /// HostInfo is a class that answers information about the host operating
18 /// system. Note that HostInfo is NOT intended to be used to manipulate or
19 /// control the operating system.
21 /// HostInfo is implemented in an OS-specific class (for example
22 /// HostInfoWindows) in a separate file, and then typedefed to HostInfo here.
23 /// Users of the class reference it as HostInfo::method().
25 /// Not all hosts provide the same functionality. It is important that
26 /// methods only be implemented at the lowest level at which they make sense.
27 /// It should be up to the clients of the class to ensure that they not
28 /// attempt to call a method which doesn't make sense for a particular
29 /// platform. For example, when implementing a method that only makes sense
30 /// on a posix-compliant system, implement it on HostInfoPosix, and not on
31 /// HostInfoBase with a default implementation. This way, users of HostInfo
32 /// are required to think about the implications of calling a particular
33 /// method and if used in a context where the method doesn't make sense, will
34 /// generate a compiler error.
