sethostname(2)							System Calls Manual						    sethostname(2)

NAME

       sethostname - Sets the name of the current host

SYNOPSIS

       int sethostname (      char *name,      int name_len );

PARAMETERS

       Points to an array of bytes where the host name is stored.  Specifies the length of the array pointed to by the name parameter.

DESCRIPTION

       The sethostname() function allows a calling process with root user authority to set the internal host name of a machine on a network.

       System host names are limited to MAXHOSTNAMELEN as defined in the /usr/include/sys/param.h file.

       The sethostid() function fails if the calling process does not have superuser privilege.

RETURN VALUES

       Upon  successful  completion, the system returns a value of 0 (zero).  If the sethostname() function fails, -1 is returned and errno is set
       to indicate the error.

ERRORS

       If the sethostname() function fails, errno may be set to one of the following values: The name parameter or the name_len parameter gives an
       address that is not valid.  The calling process does not have appropriate privilege.

NAME

       gethostname, sethostname - get or set name of current host

SYNOPSIS

       #include <unistd.h>

       int gethostname(char *name, int namelen);

       int sethostname(char *name, int namelen);

DESCRIPTION

       The gethostname() function returns the standard host name for the current processor, as previously set by sethostname(). The  namelen argu-
       ment specifies the size of the array pointed to by name. The returned name is null-terminated unless insufficient space is provided.

       The sethostname() function sets the name of the host machine to be name, which has length namelen. This call is restricted to the superuser
       and is normally used only when the system is bootstrapped.

       Host names are limited to MAXHOSTNAMELEN characters, currently 256, defined in the <netdb.h> header.

RETURN VALUES

       Upon successful completion, gethostname() and sethostname() return 0. Otherwise, they return -1 and set errno to indicate the error.

ERRORS

       The gethostname() and sethostname() functions will fail if:

       EFAULT	The name or namelen argument gave an invalid address.

       The sethostname() function will fail if:

       EPERM	The {PRIV_SYS_ADMIN} privilege was not asserted in the effective set of the calling process.
