Detach an entity from the HAM, using an entity name
#include <ha/ham.h>
int ham_detach_name( int nd,
const char *ename,
unsigned flags);
int ham_detach_name_node( const char *nodename,
const char *ename,
unsigned flags);
libham
These functions detach an attached entity (ename)
from a HAM. The entity being detached must NOT be a
self-attached entity.
The nd specifies the node identifier of the remote
node on which the entity being targeted is running,
at the time the call is made.
|
Since node identifiers are transient objects, you should obtain the
value for nd immediately before the call, using
netmgr_strtond()
or another function that converts nodenames into node identifiers. |
The ham_detach_name_node() function is used
when a nodename is used to specify a remote HAM instead of a
node identifier (nd).
There are no flags defined at this time.
This function automatically calls
ham_connect()
and
ham_disconnect() for the client.
- 0
- Success.
- -1
- An error occurred (errno is set).
- EBADF
- Error connecting to the HAM.
- EINVAL
- The name passed as an argument is invalid.
- ENOENT
- There's no entity corresponding to the name supplied.
In addition to the above errors, the HAM returns any error
it encounters while servicing the request to remove the
entity from its context.
