MEM_POOL* Delete_Mem_Pool

Description:

C++ macro replacements for new and delete using memory pools. new and delete should never be used in the compiler; these should be used instead.

Exported preprocessor macro

CXX_USE_STANDARD_NEW_AND_DELETE

If this preprocessor macro is defined, then the macros below just ignore the memory pools and call the normal new and delete.

Exported functions:

CXX_NEW(constructor, MEM_POOL*)

Use CXX_NEW instead of new. E.g.

X* x = new X(3,4);

should be replaced by

X* x = CXX_NEW(X(3,4), malloc_pool);

(or whatever appropriate pool name).

CXX_NEW_ARRAY(constructor, elements, MEM_POOL*)

Use CXX_NEW_ARRAY instead of new []. E.g.

X* x = new X[a*b];

should be replaced by

X* x = CXX_NEW_ARRAY(X, a*b, malloc_pool);

(or whatever appropriate pool name).

CXX_NEW_VARIANT(constructor, pad, MEM_POOL*)

Like CXX_NEW allocates an instance of type "constructor"

but allocates "pad" amount of extra storage

Could be viewed as X* x = (X*) malloc (sizeof(X)+pad)

Followed by a call to the constructor for X.

There is no C++ equivalent. Therefore not available when using

standard new and delete.

CXX_DELETE(pointer, MEM_POOL*)

Use CXX_DELETE instead of delete. E.g.

delete p;

should be replaced by

CXX_DELETE(p, malloc_pool);

(or whatever appropriate pool name).

CXX_DELETE_ARRAY(pointer, MEM_POOL*)

Use CXX_DELETE_ARRAY instead of delete[]. E.g.

delete[] p;

should be replaced by

CXX_DELETE_ARRAY(p, malloc_pool);

(or whatever appropriate pool name).
