Establish a client connection
A client LIBMI application can establish a client connection with the mi_open() or the mi_server_connect() function
These DataBlade
API functions
obtain a connection descriptor for the client connection. The following
table summarizes the memory operations for a connection descriptor
in a client LIBMI application.
| Memory duration | Memory operation | Function name |
|---|---|---|
| For the duration of the session | Constructor | mi_open(), mi_server_connect() |
| For the duration of the session | Destructor | mi_close() |
Important: When called within a client LIBMI application, DataBlade
API functions
always use the connection descriptor. Therefore, never send in a NULL-valued
pointer as a connection descriptor to DataBlade
API functions.
Instead, pass in the connection descriptor that the mi_open(), mi_server_connect(),
or mi_server_reconnect() function obtains.
After the client LIBMI application has established a connection, the session begins.
