Function Documentation

AFAPI af_err af_alloc_device	(	void **	ptr,
		const dim_t	bytes
	)

This device memory returned by this function can only be freed using af_free_device.

AFAPI void* af::alloc	(	const size_t	elements,
		const dtype	type
	)

Allocates memory using ArrayFire's memory manager.

Allocate memory using the ArrayFire memory manager. This function will allocate memory on the device and return a pointer to it. The memory is allocated using ArrayFire's memory manager which has some different characteristics to standard method of memory allocation

---

Parameters

[in]	elements	the number of elements to allocate
[in]	type	is the type of the elements to allocate

Returns

the pointer to the memory

Note

The device memory returned by this function is only freed if af::free() is called explicitly

T* af::alloc

(

const size_t

elements

)

Allocates memory using ArrayFire's memory manager.

Allocate memory using the ArrayFire memory manager. This function will allocate memory on the device and return a pointer to it. The memory is allocated using ArrayFire's memory manager which has some different characteristics to standard method of memory allocation

---

Parameters

[in]

elements

the number of elements to allocate

Returns

the pointer to the memory

Note

the size of the memory allocated is the number of elements * sizeof(type)

The device memory returned by this function is only freed if af::free() is called explicitly
