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.
