Memory related functions....

[james]

Your question is related to system level. you can not find any function in
standard C/C++. you need to search MEMORY API which are OS SDK provided. for
example: if your program is running at WIN32 platform:
//
MEMORYSTATUS m_mem;
::GlobalMemoryStatus(&m_mem);
//then derived as
DWORD GetPercentMemoryInUse(){return m_mem.dwMemoryLoad;};// percent of
memory in use
DWORD GetTotalPhys(){return m_mem.dwTotalPhys;};// bytes of physical memory
DWORD GetAvailPhys(){return m_mem.dwAvailPhys;};// free physical memory
bytes
DWORD GetTotalPageFile(){return m_mem.dwTotalPageFile;}; // bytes of
paging file
DWORD GetAvailPageFile(){return m_mem.dwAvailPageFile;}; // free bytes of
paging file
DWORD GetTotalVirtual(){return m_mem.dwTotalVirtual;}; // user bytes of
address space
DWORD GetAvailVirtual(){return m_mem.dwAvailVirtual;}; //free user bytes
CMem(LPMEMORYSTATUS &mem);

Hey there,

Is there a function that returns the amount of RAM free for memory
allocation?

Is there a function that will return the amount of memory your program
currently uses through memory allocation? If not, is there any simple way
of calculating this?

Thx in advance

Not in standard C++ and in general it is not possible since it will usually
vary dynamically according to factors
beyond your control - i.e. other programs.

Not in standard C++ but there often is a way.
