C++ wrappers

`mi_` prefixed implementations of various allocation functions that use C++ semantics on out-of-memory, generally calling `std::get_new_handler` and raising a `std::bad_alloc` exception on failure. More...

## Detailed Description

`mi_` prefixed implementations of various allocation functions that use C++ semantics on out-of-memory, generally calling `std::get_new_handler` and raising a `std::bad_alloc` exception on failure.

Note: use the `mimalloc-new-delete.h` header to override the new and delete operators globally. The wrappers here are mostly for convience for library writers that need to interface with mimalloc from C++.

## Data Structure Documentation

## ◆ mi_stl_allocator

struct mi_stl_allocator

### template<class T>
struct mi_stl_allocator< T >

std::allocator implementation for mimalloc for use in STL containers.

For example:

std::vector<int, mi_stl_allocator<int> > vec;
vec.push_back(1);
vec.pop_back();

## Function Documentation

## ◆ mi_new()

void* mi_new | ( | std::size_t | n | ) |
| noexcept

like mi_malloc(), but when out of memory, use `std::get_new_handler` and raise `std::bad_alloc` exception on failure.

## ◆ mi_new_aligned()

void* mi_new_aligned | ( | std::size_t | n,
|  | std::align_val_t | alignment
| ) |  |
| noexcept

like mi_malloc_aligned(), but when out of memory, use `std::get_new_handler` and raise `std::bad_alloc` exception on failure.

## ◆ mi_new_aligned_nothrow()

void* mi_new_aligned_nothrow | ( | size_t | n,
|  | size_t | alignment
| ) |  |

like `mi_malloc_aligned`, but when out of memory, use `std::get_new_handler` but return NULL on failure.

## ◆ mi_new_n()

void* mi_new_n | ( | size_t | count,
|  | size_t | size
| ) |  |
| noexcept

like mi_mallocn(), but when out of memory, use `std::get_new_handler` and raise `std::bad_alloc` exception on failure.

## ◆ mi_new_nothrow()

void* mi_new_nothrow | ( | size_t | n | ) |

like `mi_malloc`, but when out of memory, use `std::get_new_handler` but return NULL on failure.

## ◆ mi_new_realloc()

void* mi_new_realloc | ( | void * | p,
|  | size_t | newsize
| ) |  |

like mi_realloc(), but when out of memory, use `std::get_new_handler` and raise `std::bad_alloc` exception on failure.

## ◆ mi_new_reallocn()

void* mi_new_reallocn | ( | void * | p,
|  | size_t | newcount,
|  | size_t | size
| ) |  |

like mi_reallocn(), but when out of memory, use `std::get_new_handler` and raise `std::bad_alloc` exception on failure.
