DESCRIPTION
These functions are used to access or to change the domain
name of the current processor. If the null-terminated domain
name requires more than len bytes, getdomainname() returns the first
len bytes (glibc) or
returns an error (libc).
RETURN VALUE
On success, zero is returned. On error, −1 is
returned, and errno is set
appropriately.
ERRORS
- EFAULT
-
For setdomainname():
name pointed
outside of user address space.
- EINVAL
-
For getdomainname()
under libc: name is NULL or
name is longer
than len
bytes.
- EINVAL
-
For setdomainname():
len was
negative or too large.
- EPERM
-
For setdomainname():
the caller is unprivileged (Linux: does not have the
CAP_SYS_ADMIN
capability).
CONFORMING TO
POSIX does not specify these calls.
