SC5506A Operating & Programming Manual Rev 2.1.1 24
Function: sc5506a_CloseDevice
Definition: int sc5506a_CloseDevice( deviceHandle
*
devHandle)
Input: deviceHandle *devHandle (handle to the device to be closed)
Description: sc5506a_CloseDevice closes the device associated with the device handle and turns off
the “active” LED on the front panel if it is successful.
Example: Code to exercise the functions that open and and close the PXIe device:
// Declaring
#define MAXDEVICES 50
devicehandle *devHandle; //device handle
// HANDLE devHandle; // API >= 2.0
int numOfDevices; // the number of device types found
char **deviceList; // 2D to hold serial numbers of the devices found
int status; // status reporting of functions
deviceList = (
char **)malloc( sizeof ( char *)*MAXDEVICES); // MAXDEVICES serial numbers to
search
for (i=0;i<MAXDEVICES; i++)
deviceList[i] = ( char *)malloc( sizeof ( char )*SCI_SN_LENGTH); // SCI SN has 8 char
numOfDevices = sc5506a_SearchDevices(deviceList); //searches for SCI for device type
if (numOfDevices == 0)
{
printf( "No signal core devices found or cannot not obtain serial numbers\n" );
for (i = 0; i<MAXDEVICES;i++) free(deviceList[i]);
free(deviceList);
return 1;
}
printf(
"\n There are %d SignalCore %s USB devices found. \n \n" , numOfDevices,
SCI_PRODUCT_NAME);
i = 0;
while ( i < numOfDevices)
{
printf( " Device %d has Serial Number: %s \n" , i+1, deviceList[i]);
i++;
}
//** sc5506a_OpenDevice, open device 0
devHandle = sc5506a_OpenDevice(deviceList[0]);
// status = sc5506a_OpenDevice(deviceList[0], &devHandle); //API >= 2.0
// Free memory
for (i = 0; i<MAXDEVICES;i++) free(deviceList[i]);
free(deviceList); // Done with the deviceList
//
// Do something with the device
// Close the device
status = sc5506a_CloseDevice(devHandle);
