Device Information Functions [LJM User's Guide]
LJM_GetHandleInfo
LJM_GetHandleInfo returns details about a device handle.
Device Discovery
The ListAll functions search for available LabJack device connections. LJM_ListAll
and LJM_ListAllS
are the same function, except that LJM_ListAll uses integer parameters to filter what connections are searched for, while LJM_ListAllS uses string parameters to do the same. LJM_ListAllExtended allows arbitrary device registers to be queried.
Device Reconnection
In a real-world setup, device connections can intermittently fail. LJM does its best to reconnect to devices and LJM_RegisterDeviceReconnectCallback can notify client code when reconnect has occurred.
