16 The gethostname() function returns the standard host name for the cur‐
17 rent machine. The namelen argument specifies the size of the array
18 pointed to by the name argument. The returned name is null-terminated,
19 except that if namelen is an insufficient length to hold the host name,
20 then the returned name is truncated and it is unspecified whether the
21 returned name is null-terminated.
