Detailed Description

Allocates and returns a pointer to device memory.

This function will allocate memory on the device and return a pointer to the memory location. This data is not managed by the array and therefor needs to be deallocated using the array::free() function. The pointer can be used to create an array object using one of the Constructors.

Allocate device memory array of elements.

float *dptr = array::alloc<float>(10); // actually 4*10=40 bytes
array X = array(10, dptr, afDevice);
print(X); // print (uninitialized) values
