I want a function in c++ that returns available memory.?

for example i get this memory:





int* p=new[100000];





i want to see the available memory befor and after it.

I want a function in c++ that returns available memory.?
For 32 bit Windows:





DWORD ramsize;


DWORD freesize;


MEMORYSTATUS lpBuffer;





lpBuffer.dwLength = sizeof(MEMORYSTATUS);





GlobalMemoryStatus(%26amp;lpBuffer);


ramsize = lpBuffer.dwTotalPhys;


freesize = lpBuffer.dwAvailPhys;
Reply:There is no such native function in c++; it depends on the OS. You need to look in the Linux or Windows documentation for a suitable function. BTW, even if such a function were available, you *might* not get the result you're looking for. Typically an OS might maintain a memory pool on a per-process basis to speed memory allocation. So you might find that the available memory is unchanged after your new[] call.
