gethostname(3c)

Standard C Library Functions                                   gethostname(3C)



NAME
       gethostname, sethostname - get or set name of current host

SYNOPSIS
       #include <unistd.h>

       int gethostname(char *name, size_t namelen);


       int sethostname(char *name, size_t namelen);

DESCRIPTION
       The  gethostname() function returns the standard host name for the cur‐
       rent zone, as previously set by  sethostname().  The  namelen  argument
       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 host name of the currrent  zone  to
       be   name,   which   has   length   namelen.  This  call  requires  the
       {PRIV_SYS_ADMIN} privilege and is normally used only when the system is
       booted.


       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 argument is an invalid address.



       The sethostname() function will fail if:

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