<h3>GETHOSTNAME(2)      Linux Programmer's Manual      GETHOSTNAME(2)
</h3>

<h3>NAME
</h3>       gethostname, sethostname - get/set host name

<h3>SYNOPSIS
</h3>       #include &lt;unistd.h&gt;

       int gethostname(char *name, size_t len);
       int sethostname(const char *name, size_t len);

<h3>DESCRIPTION
</h3>       These  functions  are used to access or to change the host
       name of the current processor.

<h3>RETURN VALUE
</h3>       On success, zero is returned.  On error, -1  is  returned,
       and errno is set appropriately.

<h3>ERRORS
</h3>       EINVAL len  is negative or, for sethostname, len is larger
              than the maximum allowed size, or, for  gethostname
              on Linux/i386, len is smaller than the actual size.

       EPERM  For sethostname, the caller was not the  superuser.

       EFAULT name is an invalid address.

<h3>CONFORMING TO
</h3>       POSIX.1  does  not  define  these  functions,  but ISO/IEC
       9945-1:1990 mentions them in B.4.4.1.

<h3>BUGS
</h3>       Some other  implementations  of  gethostname  successfully
       return len bytes even if name is longer.  Linux/Alpha com-
       plies with this behaviour.  Linux/i386,  however,  returns
       EINVAL in this case (as of DLL 4.6.27 libraries).

<h3>NOTES
</h3>       Under  Linux/Alpha,  gethostname  is a system call.  Under
       Linux/i386, gethostname  is  implemented  at  the  library
       level by calling uname(2).
