The Windows Sockets gethostname
function returns the standard host name for the local machine.
int gethostname (
| char FAR * name,
| int namelen
[out] A pointer to a buffer that will receive the host name.
[in] The length of the buffer.
This routine returns the name of the local host into the buffer specified by
parameter. The host name is returned as a null-terminated string. The form of
the host name is dependent on the Windows Sockets provider
it can be a simple host name, or it can be a fully qualified domain name.
However, it is guaranteed that the name returned will be successfully parsed by gethostbyname
If no local host name has been configured gethostname
must succeed and return a token host name that gethostbyname
If no error occurs, gethostname
returns zero. Otherwise, it returns SOCKET_ERROR and a specific error code can
be retrieved by calling WSAGetLastError
||The name argument is not a valid part of the user address space, or the buffer size
specified by namelen argument is too small to hold the complete host name.
||A successful WSAStartup must occur before using this function.
||The network subsystem has failed.
||A blocking Windows Sockets 1.1 call is in progress, or the service provider is
still processing a callback function.
