    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);

    Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

    getdomainname(), setdomainname(): _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).
     

    CONFORMING TO

    POSIX does not specify these calls.
