What about implementing sethostname instead?
extern "C" int
sethostname (const char *name, size_t len)
{
WCHAR wname[MAX_COMPUTERNAME_LENGTH + 1];
sys_mbstowcs (wname, MAX_COMPUTERNAME_LENGTH + 1, name, len);
if (!SetComputerNameEx (ComputerNamePhysicalDnsHostname, wname))
{
__seterrno ();
return -1;
}
return 0;
}
