Function opencl3::context::context::create_context_from_type

pub fn create_context_from_type(
    device_type: u64, 
    properties: *const isize, 
    pfn_notify: Option<extern "C" fn(*const i8, *const c_void, usize, *mut c_void)>, 
    user_data: *mut c_void
) -> Result<*mut c_void, i32>

Create an OpenCL context from a specific device type.
Calls clCreateContextFromType to create an OpenCL context.

• device_type - the type of OpenCL device, see: Device Types.
• properties - a null terminated list of cl_context_properties, see: Context Properties.
• pfn_notify - an optional callback function that can be registered by the application.
• user_data - passed as the user_data argument when pfn_notify is called.

returns a Result containing the new OpenCL context or the error code from the OpenCL C API function.
