USHORT WENTRY_C S5StarteVerbindung(H1_CONNECT_PARAMS W_POINTER cr)
The
S5StarteVerbindung
function is used to define a connection to another system on the
network.
You must establish a connection by means of
S5StarteVerbindung
before you can use it.
Parameters
cr
pointer to a structure containing connection parameters.
The value Vnr is set if the function completes without error. This
represents the connection number. However, this number will only be
returned if:
- all drivers have been installed.
- the connection parameters are correct.
- the remote station acknowledges the connection if required by the
connection parameters.
A valid connection number does not imply that the connection to the
partner has been established. This also depends on the connection
parameters.
Returns
0
H1_WAIT_CONNECT
H1_BAD_CR_PARAMS
H1_NO_SLOT
H1_NO_DRIVER
H1_NO_ADAPTER
