DESCRIPTION

21       The gethostname() function shall return the standard host name for  the
22       current  machine.  The  namelen  argument shall specify the size of the
23       array pointed to by the name argument.   The  returned  name  shall  be
24       null-terminated,  except  that  if namelen is an insufficient length to
25       hold the host name, then the returned name shall be truncated and it is
26       unspecified whether the returned name is null-terminated.
27
28       Host names are limited to {HOST_NAME_MAX} bytes.
