Hi.
How can I know the amount of RAM allocated by a vector?
For example:
string[8][1000] array;
for(int i=0;i<1000;i++) {
array[i]=["","","","","","","",""];
}
how can I know the amount of bytes of above matrix?
array.sizeof. BUT I would caution that you have used fixed-sized arrays
so they will NOT be allocated on the heap, but rather on the stack (or
thread-local storage if it's a global).
For a variable-sized array, such as string[8][], the .sizeof property is
always going to be 2 words.
For that case, you need to use the GC to ask for the block size:
writeln(GC.sizeof(array.ptr));
Can I clean the memory ofter his use, without use GC?
It depends on where you put it. But generally D does not give back any
memory to the OS unless asked to do so.
But maybe that's not your question?
