## Detailed Description

Allocating aligned memory blocks.

## Macro Definition Documentation

## ◆ MI_ALIGNMENT_MAX

#define MI_ALIGNMENT_MAX

The maximum supported alignment size (currently 1MiB).

## Function Documentation

## ◆ mi_calloc_aligned()

void* mi_calloc_aligned | ( | size_t | count,
|  | size_t | size,
|  | size_t | alignment
| ) |  |

## ◆ mi_calloc_aligned_at()

void* mi_calloc_aligned_at | ( | size_t | count,
|  | size_t | size,
|  | size_t | alignment,
|  | size_t | offset
| ) |  |

## ◆ mi_malloc_aligned()

void* mi_malloc_aligned | ( | size_t | size,
|  | size_t | alignment
| ) |  |

Allocate size bytes aligned by alignment.

Parameters

  size | number of bytes to allocate.
  alignment | the minimal alignment of the allocated memory. Must be less than MI_ALIGNMENT_MAX.

Returns
  pointer to the allocated memory or NULL if out of memory. The returned pointer is aligned by alignment, i.e. `(uintptr_t)p % alignment == 0`.

Returns a unique pointer if called with size 0.

## ◆ mi_malloc_aligned_at()

void* mi_malloc_aligned_at | ( | size_t | size,
|  | size_t | alignment,
|  | size_t | offset
| ) |  |

Allocate size bytes aligned by alignment at a specified offset.

Parameters

  size | number of bytes to allocate.
  alignment | the minimal alignment of the allocated memory at offset.
  offset | the offset that should be aligned.

Returns
  pointer to the allocated memory or NULL if out of memory. The returned pointer is aligned by alignment at offset, i.e. `((uintptr_t)p + offset) % alignment == 0`.

Returns a unique pointer if called with size 0.
