I am not quite sure the true meaning of your question. I try to answer
as much as I can.
Cint and ROOT/CINT support following ANSI C standard function.
void *malloc(size_t size);
void free(void* ptr);
and C++ new/delete operators.
void* operator new(size_t size);
void* operator new(size_t size,void* arena);
void operator delete(void* ptr);
For memory allocation, you can use either of following.
1) double *pdbl = (double*)malloc(sizeof(double));
free((void*)pdbl);
2) double *pdbl = new double;
delete pdbl;
3) char buf[100];
double *pdbl = new((void*)buf) double;
// do not delete pbl in this case
This is almost full C/C++ spec. Limitation is that you can not overload
operator new/delete in interpreted code.
Thank you
