Function Documentation

int contacts_connect ( void  )

Connects to the contacts service.

Since :
2.3
Remarks:
Connection opening is necessary to access the contacts server such as fetching, inserting, or updating records.
The execution of contacts_connect() and contacts_disconnect() could slow down your application. So it is not recommended to call them frequently.
Returns:
0 on success, otherwise a negative error value
Return values:
CONTACTS_ERROR_NONESuccessful
CONTACTS_ERROR_IPCIPC error
CONTACTS_ERROR_OUT_OF_MEMORYOut of memory
CONTACTS_ERROR_NOT_SUPPORTEDNot supported
CONTACTS_ERROR_SYSTEMSystem error
CONTACTS_ERROR_INTERNALInternal error
See also:
contacts_disconnect()
int contacts_connect_on_thread ( void  )

Connects to the contacts service with a connection on another thread.

Since :
2.3
Remarks:
Opening connection is necessary to access the contact server and to perform operations such as fetching, inserting, or updating records.
On multiple thread environment with contacts_connect(), request can be failed in one thread, while another request is working by the connection in the other thread. To prevent request fail, contacts_connect_on_thread() is recommended. Then new connection is set for the thread.
Returns:
0 on success, otherwise a negative error value
Return values:
CONTACTS_ERROR_NONESuccessful
CONTACTS_ERROR_IPCIPC error
CONTACTS_ERROR_OUT_OF_MEMORYOut of memory

int contacts_connect_with_flags ( unsigned int  flags)

Connects to the contacts service.

Since :
2.3
Parameters:
[in]flagsConnection flag
Remarks:
Connection opening is necessary to access the contacts server such as fetching, inserting, or updating records.
Before contacts-service daemon is ready, if you call contacts_connect(), it will fail. To prevent it, if you call this API with CONTACTS_CONNECT_FLAG_RETRY flags, it will retry several time.
To close the connection, contacts_disconnect() should be called.
Returns:
0 on success, otherwise a negative error value
Return values:
CONTACTS_ERROR_NONESuccessful
CONTACTS_ERROR_IPCIPC error
CONTACTS_ERROR_OUT_OF_MEMORYOut of memory
