Function Documentation

int calendar_connect ( void  )

Connects to the calendar service.

Since :

Remarks:
Opening the connection is necessary to access the calendar database and perform operations such as fetching, inserting, or updating records.
The execution of calendar_connect() and calendar_disconnect() could slow down your application, so you are recommended not to call them frequently.
Returns:
0 on success, otherwise a negative error value
Return values:
CALENDAR_ERROR_NONESuccessful
CALENDAR_ERROR_DB_FAILEDDatabase operation failure
CALENDAR_ERROR_OUT_OF_MEMORYOut of memory
CALENDAR_ERROR_INVALID_PARAMETERInvalid parameter

Since :
3.0
Remarks:
Opening a connection is necessary to access the calendar database and perform operations such as fetching, inserting, or updating records.
On a thread environment with calendar_connect(), request in one thread could fail, while another request connection is working in the other thread. To prevent request failure, calendar_connect_on_thread() is recommended.
Returns:
