mvncGetDeviceName()

Type	Function
Header	mvnc.h
Library	libmvnc.so
Return	mvncStatus
Version	1.0
See also	mvncOpenDevice

Overview

This function is used to get the name of a particular Intel® Movidius™ NCS device. Typical usage is to call the function repeatedly, starting with index = 0, and incrementing the index each time until an error is returned. These successive calls will give you the names of all the devices in the system.

Prototype

mvncStatus mvncGetDeviceName(int index, char* name, unsigned int nameSize);

Parameters

Name	Type	Description
index	int	Index of the device for which the name should be retrieved.
name	char*	Pointer to a character buffer into which the name will be copied. This buffer should be allocated by the caller.
nameSize	unsigned int	The number of characters allocated to the buffer pointed to by the name parameter.

Return

This function returns an appropriate value from the mvncStatus enumeration.

Known Issues

Example

The following example shows how to get the name of all Intel® Movidius™ NCS devices attached to the system. mvncGetDeviceName is called repeatedly until it returns MVNC_DEVICE_NOT_FOUND.

#include <stdio.h>
extern "C" 
{
#include <mvnc.h>
}
// somewhat arbitrary buffer size for the device name
#define NAME_SIZE 100
int main(int argc, char** argv)
{
    mvncStatus retCode;
    int deviceCount = 0;
    char devName[NAME_SIZE];
    while ((retCode = mvncGetDeviceName(deviceCount, devName, NAME_SIZE)) != MVNC_DEVICE_NOT_FOUND)
    {
        printf("Found NCS device named: \"%s\"\n", devName); 
        deviceCount++;
    }
    printf("Total number of NCS devices found: %d\n", deviceCount);
}

Output from the example code above with two Intel® Movidius™ NCS devices in the system.

Found NCS device named: "2.3"
Found NCS device named: "1"
Total number of NCS devices found: 2
