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 delete()

void operator delete ( void *  ,
void *   
)
inlinenoexcept

Definition at line 196 of file new.

◆ operator delete[]()

void operator delete[] ( void *  ,
void *   
)
inlinenoexcept

Definition at line 197 of file new.

◆ operator new() [1/2]

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.

◆ operator new() [2/2]

void * operator new ( std::size_t  ,
void *  __p 
)
inlinenoexcept

Definition at line 187 of file new.

◆ operator new[]()

void * operator new[] ( std::size_t  ,
void *  __p 
)
inlinenoexcept

Definition at line 190 of file new.
