Call mxfSystemErrorStringGet() to transform the return code into a text string.
Server Attributes
Ethernet Server supports the following attributes:
Keep Alive
The KMXF_SERVER_KEEP_ALIVE attribute holds the keep alive mechanism state. When enabled, connection timeout is fired if no activity has been detected for 60 seconds. Network timeout condition can happen when debugging an Ethernet application and staying on a breakpoint for longer than the timeout value. In that case, disabling the keep alive mechanism will avoid this condition.
| Constant | Description |
| VMXF_ENABLE | Keep alive is enabled (default) |
| VMXF_DISABLE | Keep alive is disabled |
Allow Reconnection
When enabled, the KMXF_SERVER_ALLOW_RECONNECTION_EXCLUSIVE_CLIENT attribute allows an exclusive client to reconnect. This can be useful in development when the application is run in a container and terminates improperly without calling mxfServerDisconnect(), but the process is still alive (VIs in LabVIEW are such a case). This attribute is global to the server, so any client can change it.
| Constant | Description |
| VMXF_ENABLE | Reconnection is allowed |
| VMXF_DISABLE | Reconnection is not allowed (default) |
