This is a perfectly doable thing.
Something like:
uint64_t GetRAMPhysicalUsedByCurrentProcess() {
task_vm_info_data_t vmInfo;
mach_msg_type_number_t count = TASK_VM_INFO_COUNT;
if (task_info(mach_task_self(), TASK_VM_INFO, (task_info_t)&vmInfo, &count) == KERN_SUCCESS) {
return vmInfo.phys_footprint;
}
return 0;
}

Thanks! Do you have a similar code for GetRAMVirtualUsedByCurrentProcess()
? It seems that's what Celero is currently measuring during testing.

Perhaps something like this. You should look at the API to be sure.
#include <iostream>
#include <mach/mach.h>
#include <mach/task_info.h>
uint64_t GetVirtualMemoryUsed() {
mach_task_basic_info_data_t taskInfo;
mach_msg_type_number_t infoCount = MACH_TASK_BASIC_INFO_COUNT;
kern_return_t kr = task_info(mach_task_self(), MACH_TASK_BASIC_INFO, reinterpret_cast<task_info_t>(&taskInfo), &infoCount);
if (kr != KERN_SUCCESS) {
std::cerr << "Error: Unable to get task_info. Error code: " << kr << std::endl;
return 0;
}
return taskInfo.virtual_size;
}
int main() {
uint64_t virtualRAMUsed = GetVirtualMemoryUsed();
std::cout << "Virtual RAM used by current process: " << virtualRAMUsed << " bytes." << std::endl;
return 0;
}
