GETDOMAINNAME
NAME SYNOPSIS DESCRIPTION RETURN VALUE ERRORS CONFORMING TO SEE ALSO
getdomainname, setdomainname - get/set domain name
#include
int getdomainname(char *name, size_t len); int setdomainname(const char *name, size_t len);
These functions are used to access or to change the domain name of the current processor. If the NUL-terminated domain name requires more than len bytes, getdomainname returns the first len bytes (glibc) or returns an error (libc).
On success, zero is returned. On error, -1 is returned, and errno is set appropriately.
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 was not the superuser.
EFAULT
For setdomainname: name pointed outside of user address space.
POSIX does not specify these calls.
