Opens deviceFile and allocates a small structure to record the device name, file descriptor, and function pointers for manipulating the allocator. The deviceFile must be /dev/allegroIP. DmaAlloc_Create does not take ownership of the device file string. When the allocator is no longer needed, AL_Allocator_Destroy should be called to free associated system resources.
Return
Returns a pointer to an allocator if successful, or NULL otherwise.
