scha_cluster_getzone(3HA)				 Sun Cluster HA and Data Services				 scha_cluster_getzone(3HA)

NAME

       scha_cluster_getzone - zone name access function

SYNOPSIS

       cc [flags...] -I /usr/cluster/include file -L /usr/cluster/lib  -l  scha
       #include <scha.h>

	scha_err_t scha_cluster_getzone(char **zonename);

DESCRIPTION

       The  scha_cluster_getzone() function returns a string that identifies the zone from which the function is called. If you call this function
       in a non-global zone, the zone name and the node name are returned, in the format nodename:zonename. If	you  call  this  function  in  the
       global  zone, only the node name is returned. The node name is not necessarily the same as the Solaris system name. The function returns an
       error status.  If successful, the function also returns a string that contains the node name and the zone name  in  the	location  that	is
       pointed to by the zonename argument.

       If the call fails, the zonename argument is set to NULL. The caller of scha_cluster_getzone() is responsible for freeing the memory that is
       allocated for the returned string by using the standard C library function free(3C). Freeing the memory is required only  if  the  function
       succeeds.

RETURN VALUES

       The scha_cluster_getzone() function returns the following values:

       0		   The function succeeded.

       nonzero		   The function failed.

ERRORS

       SCHA_ERR_NOERR			   The function succeeded.

       See scha_calls(3HA) for a description of other error codes.

EXAMPLES

       Example 1 Using the scha_cluster_getzone() Function

	       scha_err_t  err_code;
	      char *zonename;
	      err_code = scha_cluster_getzone(&zonename);
	      ...
	      if (zonename != NULL) free(zonename);
