API | API Description | Input Parameters | Return Values |
---|---|---|---|
int ifc_qdma_device_get(int port, struct ifc_qdma_device **qdev) | Based on the port number, API returnS corresponding device context to the application. Application must maintain the device context and use it for further operations. When the application is done with I/O, it releases the context by using ifc_qdma_device_put API. |
port - port number of the device, which is returned by ifc_mcdma_port_by_name API qdev - Address of the pointer to device context |
Updates device context and returns 0 on success negative otherwise |
