Request or release system control.
unsigned int ibrsc (int ud, int v)
ibrsc v
ud | Board or device descriptor |
v | Determines if system control is to be requested or released |
Function Return | The value of Ibsta |
ibrsc requests or releases the capability to send Interface Clear (IFC) and Remote Enable (REN) messages to devices. If v is zero, the board releases system control, and calls requiring System Controller capability are not allowed. If v is non-zero, calls requiring System Controller capability are subsequently allowed. If no error occurs during the call, Iberr contains the previous System Controller state of the board.
