* Name: netdb_gethostname
*
* Description:
* The netdb_gethostname() function will return the standard host name for
* the current machine. The namelen argument will specify the size of the
* array pointed to by the name argument. The returned name will be null-
* terminated, except that if namelen is an insufficient length to hold the
* host name, then the returned name will be truncated and it is
* unspecified whether the returned name is null-terminated.
*
* Host names are limited to {HOST_NAME_MAX} bytes.
*
* Input Parameters:
* name - The user-provided buffer to receive the host name.
* namelen - The size of the user provided buffer in bytes.
*
* Returned Value:
* Upon successful completion, 0 will be returned; otherwise, -1 will be
* returned. No errors are defined; errno variable is not set.

* Name: netdb_sethostname
*
* Description:
*
* netdb_sethostname() sets the hostname to the value given in the
* character array name. The len argument specifies the number of bytes in
* name. (Thus, name does not require a terminating null byte.)
*
* Input Parameters:
* name - The user buffer to providing the new host name.
* namelen - The size of the user buffer in bytes.
*
* Returned Value:
* Upon successful completion, 0 will be returned; otherwise, -1 will be
* returned. No errors are defined; errno variable is not set.
