## Function Documentation

void __TBB_EXPORTED_FUNC scalable_aligned_free | ( | void * | ptr | ) |

The "_aligned_free" analogue.

void* __TBB_EXPORTED_FUNC scalable_aligned_malloc | ( | size_t | size,
|  | size_t | alignment |
| ) |  |  |

The "_aligned_malloc" analogue.

void* __TBB_EXPORTED_FUNC scalable_aligned_realloc | ( | void * | ptr,
|  | size_t | size,
|  | size_t | alignment |
| ) |  |  |

The "_aligned_realloc" analogue.

void* __TBB_EXPORTED_FUNC scalable_calloc | ( | size_t | nobj,
|  | size_t | size |
| ) |  |  |

The "calloc" analogue complementing scalable_malloc.

void __TBB_EXPORTED_FUNC scalable_free | ( | void * | ptr | ) |

The "free" analogue to discard a previously allocated piece of memory.

Referenced by tbb::scalable_allocator< T >::deallocate().

void* __TBB_EXPORTED_FUNC scalable_malloc | ( | size_t | size | ) |

The "malloc" analogue to allocate block of memory of size bytes.

Referenced by tbb::scalable_allocator< T >::allocate().

size_t __TBB_EXPORTED_FUNC scalable_msize | ( | void * | ptr | ) |

The analogue of _msize/malloc_size/malloc_usable_size. Returns the usable size of a memory block previously allocated by scalable_*, or 0 (zero) if ptr does not point to such a block.

int __TBB_EXPORTED_FUNC scalable_posix_memalign | ( | void ** | memptr,
|  | size_t | alignment,
|  | size_t | size |
| ) |  |  |

The "posix_memalign" analogue.

void* __TBB_EXPORTED_FUNC scalable_realloc | ( | void * | ptr,
|  | size_t | size |
| ) |  |  |

The "realloc" analogue complementing scalable_malloc.
