## Detailed Description

Allocate pinned memory using ArrayFire's memory manager.

These functions allocate page locked memory. This type of memory has better performance characteristics but require additional care because they are a limited resource.

## Function Documentation

## § af_alloc_pinned()

AFAPI af_err af_alloc_pinned | ( | void ** | ptr,
|  | const dim_t | bytes
| ) |  |

## § pinned() [1/2]

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

Allocate pinned memory using ArrayFire's memory manager.

These functions allocate page locked memory. This type of memory has better performance characteristics but require additional care because they are a limited resource.

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

## § pinned() [2/2]

T* af::pinned | ( | const size_t | elements | ) |

These functions allocate page locked memory. This type of memory has better performance characteristics but require additional care because they are a limited resource.

Parameters

  [in] | elements | the number of elements to allocate

Returns
  the pointer to the memory
