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.
