Standard C Library (libc.a)
int setdomainname ( Name, Namelen)
The setdomainname subroutine sets the name of the domain for the host machine. It is normally used when the system is bootstrapped. You must have root user authority to run this subroutine.
The purpose of domains is to enable two distinct networks that may have host names in common to merge. Each network would be distinguished by having a different domain name. At the current time, only Network Information Service (NIS) makes use of domains set by this subroutine.
Note: Domain names are restricted to 256 characters.
|Name||Specifies the domain name to be set.|
|Namelen||Specifies the size of the array pointed to by the Name parameter.|
If the call succeeds, a value of 0 is returned. If the call is unsuccessful, a value of -1 is returned and an error code is placed in the errno global variable.
The following error may be
returned by this subroutine:
|EFAULT||The Name parameter gave an invalid address.|
|EPERM||The caller was not the root user.|
The setdomainname subroutine is part of Base Operating System (BOS) Runtime.
All applications containing the setdomainname subroutine must be compiled with _BSD set to a specific value. Acceptable values are 43 and 44. In addition, all socket applications must include the BSD libbsd.a library.
