GETHOSTNAME(2)      Linux Programmer's Manual      GETHOSTNAME(2)
+

+
+
NAME
+
       gethostname, sethostname - get/set host name
+
+
SYNOPSIS
+
       #include <unistd.h>
+
+       int gethostname(char *name, size_t len);
+       int sethostname(const char *name, size_t len);
+
+
DESCRIPTION
+
       These  functions  are used to access or to change the host
+       name of the current processor.
+
+
RETURN VALUE
+
       On success, zero is returned.  On error, -1  is  returned,
+       and errno is set appropriately.
+
+
ERRORS
+
       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.
+
+
CONFORMING TO
+
       POSIX.1  does  not  define  these  functions,  but ISO/IEC
+       9945-1:1990 mentions them in B.4.4.1.
+
+
BUGS
+
       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).
+
+
NOTES
+
       Under  Linux/Alpha,  gethostname  is a system call.  Under
+       Linux/i386, gethostname  is  implemented  at  the  library
+       level by calling uname(2).
