## Detailed Description

This is a Standard C++ Library header.

The header `new` defines several functions to manage dynamic memory and handling memory allocation errors; see https://gcc.gnu.org/onlinedocs/libstdc++/manual/dynamic_memory.html for more.

Definition in file new.

## Function Documentation

## operator new()

void* operator new | ( | std::size_t |  | ) |

These are replaceable signatures:

- normal single new and delete (no arguments, throw `bad_alloc` on error)
- normal array new and delete (same)
- `nothrow` single new and delete (take a `nothrow` argument, return `NULL` on error)
- `nothrow` array new and delete (same)

Placement new and delete signatures (take a memory address argument, does nothing) may not be replaced by a user's program.
