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 http://gcc.gnu.org/onlinedocs/libstdc++/18_support/howto.html#4 for more.

Definition in file new.

void operator delete ( void *  ,
const std::nothrow_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.
