I need to check for free RAM before performing a specific operation.
I've Googled and checked in the docs and I suspect its my
terminology that's just out of whack.
So what is the best way to find out how much available RAM is
available in a Cocoa app?
You can also get some information with these calls, although I don't
know how useful it will be in your situation:
// Amount of physical memory installed -- requires 10.5
unsigned long long memory = [[NSProcessInfo processInfo]
physicalMemory];
// Amount of memory allocated to user space
unsigned long long memory;
size_t mem_len = sizeof(memory);
int mib[2];
mib[0] = CTL_HW;
mib[1] = HW_USERMEM;
if( sysctl(mib, 2, &memory, &mem_len, NULL, 0) == -1 ) {
perror("sysctl");
}
It doesn't really tell you about what's actually available to the
application, though :/
