* add smartheap * cmake: bump even further * this seemed to be necessary but now it isn't? ok * cmake: force include smrtheap.hpp Co-authored-by: Anonymous Maarten <madebr@users.noreply.github.com> * cmake: force include smrtheap.hpp 2 Co-authored-by: Anonymous Maarten <madebr@users.noreply.github.com> * remove compiler defs - unnecessary if force-including anyway * cmake: use interface for cleaner code --------- Co-authored-by: Anonymous Maarten <madebr@users.noreply.github.com>

|
|
// COMMENTS:
|
|
// - Include this header file to call the SmartHeap-specific versions of
|
|
// operators new (i.e. with placement syntax), to:
|
|
// o allocate from a specific memory pool;
|
|
// o specify allocation flags, such as zero-initialization;
|
|
// o resize an allocation.
|
|
//
|
|
// - If you include this header file, you must compile and link shnew.cpp, or
|
|
// link with one of the SmartHeap static operator new libraries:
|
|
// sh[l|d]XXXX.lib
|
|
//
|
|
// - Can be used in both EXEs and DLLs.
|
|
//
|
|
// - For 16-bit x86 platforms, use only in large or compact memory model.
|
|
//
|
|
// - If you do not want to use SmartHeap's global operator new but you do
|
|
// want to use SmartHeap's other facilities in a C++ application, then
|
|
// include the smrtheap.h header file but do not include this header file,
|
|
// and do not link with shnew.cpp. The two ".Xpp" files are present
|
|
// ONLY for the purpose of defining operator new and operator delete.
|
|
//
|
|
// - Use the MemDefaultPool global variable to refer to a memory pool to pass
|
|
// to SmartHeap functions that accept a pool as a parameter,
|
|
// e.g. MemPoolCount, MemPoolSize, MemPoolWalk, etc.
