NAME
getdomainname, setdomainname - get/set domain nameSYNOPSIS
#include <unistd.h>int getdomainname(char *name, size_t len);
int setdomainname(const char *name, size_t len);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
getdomainame(), setdomainame(): _BSD_SOURCE || (_XOPEN_SOURCE && _XOPEN_SOURCE < 500)
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).
