NAME

getdomainname, setdomainname ? get/set domain name

SYNOPSIS

#include <unistd.h>

int getdomainname(char *name, size_t len);
int setdomainname(const char *
name, size_t len);

DESCRIPTION

These functions are used to access or to change the domain name of the current processor.

RETURN VALUE

On success, zero is returned. On error, ?1 is returned, and errno is set appropriately.

ERRORS

EINVAL

For getdomainname, name points to NULL or name is longer than len.

EPERM

For setdomainname, the caller was not the superuser.

EINVAL

For setdomainname, len was too long.

CONFORMING TO

POSIX does not specify these calls.

BUGS

getdomainname is not compliant with other implementations, since they always return len bytes, even if name is longer. Linux, however, returns EINVAL in this case (as of DLL 4.4.1 libraries).

NOTES

Under Linux, getdomainname is implemented at the library level by calling uname(2).
