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.

Function Documentation

operator delete() [1/3]

void operator delete ( void *  )

noexcept

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 delete() [2/3]

void operator delete ( void *  , const std::nothrow_t &    )

noexcept

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 delete() [3/3]

void operator delete ( void *  , void *    )

inlinenoexcept

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 delete[]() [1/3]

void operator delete[] ( void *  )

noexcept

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 delete[]() [2/3]

void operator delete[] ( void *  , const std::nothrow_t &    )

noexcept

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 delete[]() [3/3]

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

inlinenoexcept

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.
