NAME

     gethostname, sethostname -- get/set name of current host

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <unistd.h>

     int
     gethostname(char *name, size_t namelen);

     int
     sethostname(const char *name, size_t namelen);

DESCRIPTION

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

     sethostname() sets the name of the host machine to be name, which has length namelen.  This call is restricted to the super-user and is nor-
     mally used only when the system is bootstrapped.

RETURN VALUES

     If the call succeeds a value of 0 is returned.  If the call fails, a value of -1 is returned and an error code is placed in the global loca-
     tion errno.

ERRORS

     If the gethostname() or sethostname() functions fail, they will set errno for any of the errors specified for the routine sysctl(3).

SEE ALSO

STANDARDS

HISTORY

     The gethostname function call appeared in 4.2BSD.

BUGS

     Host names are limited to MAXHOSTNAMELEN (from <sys/param.h>) characters including null-termination, currently 256.
