Detailed Description

Returns an integer indicating the backends loaded successfully.

The number returned denotes the backends available according to the table:

Return Value	Backends Available
0	None
1	CPU
2	CUDA
3	CPU and CUDA
4	OpenCL
5	CPU and OpenCL
6	CUDA and OpenCL
7	CPU, CUDA and OpenCL

To convert the integer back into bools for each device, use the following code

int backends = af::getAvailableBackends();
 
bool cpu    = backends & AF_BACKEND_CPU;
bool cuda   = backends & AF_BACKEND_CUDA;
bool opencl = backends & AF_BACKEND_OPENCL;
