#include <unistd.h> int getdomainname(char *name, size_t len); int setdomainname(const char *name, size_t len);

POPIS / INSTRUKCE

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).

NÁVRATOVÁ HODNOTA

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

CHYBY / ERRORY

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).

ODPOVÍDAJÍCÍ
