How to correctly print values from clGetDeviceInfo

I am trying to print out the type of local memory: 

cl_int err;
cl_device_local_mem_type type;
err = clGetDeviceInfo(
deviceId,
CL_DEVICE_LOCAL_MEM_TYPE,
sizeof(cl_device_local_mem_type),
&type,
0 );

printf ("Memory type is %s=". type);

This is not working. Also if I use &type, even then it is working.

Do I need to do some type casting ? Please help me resolve this.

The cl_device_local_mem_type type is just an unsigned integer, so you should be printing it with %u, not %s.

cl_int err;
cl_device_local_mem_type type;
err = clGetDeviceInfo(
deviceId,
CL_DEVICE_LOCAL_MEM_TYPE,
sizeof(cl_device_local_mem_type),
&type,
0 );

printf ("Memory type is %u=", type);

You'll get either 1 or 2 back, which you can check in the cl.h header:

#define CL_LOCAL                                    0x1
#define CL_GLOBAL                                   0x2
