An exception class that is thrown when a CSocket::Connect is done to a host that demonstrably does not exist. This may be because the host provided to CSocket::Connect is incorrect or because the host is not currently alive.


CTCPNoSuchHost(const std::string& hostname, const std::string& Doing);

Constructs the exception. hostname is the DNS name or dotted IP address of the host that does not exist. Doing is a string that describes what the library was doing when this object was constructed/thrown.

const int gethErrno();

TCP/IP networking reports some errors via the h_errno global variable. The value of this variable is captured and stored by the exception's constructor. This method returns the value of h_errno as it was at construction time.

http://linux.die.net/man/3/h_errno contains a description of the values of h_errno.

const std::string getHost();

Returns the host string passed in to the contructor. Typically this will designate the host to which a connection could not be formed.

virtual const const char * ReasonText ();

Returns a human readable error message that desribes the failure.

virtual const int ReasonCode();

Overrides the base class's method and returns the saved h_errno
