To protect xournal from memory overflows I try to determine how much memory is free at the moment that a file is opened in xournal. I am using the output of the /proc/meminfo, but it is confusing me. I browsed some time on the internet, and I could only find what the individual field mean, but not how to determine the actual amount of free memory.
The output looks like this (on the emulator):
MemTotal: 126796 kB MemFree: 71936 kB Buffers: 1508 kB Cached: 29148 kB SwapCached: 0 kB Active: 33464 kB Inactive: 15316 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 528 kB Writeback: 0 kB AnonPages: 18152 kB Mapped: 11740 kB Slab: 3408 kB SReclaimable: 1452 kB SUnreclaim: 1956 kB PageTables: 680 kB NFS_Unstable: 0 kB Bounce: 0 kB CommitLimit: 63396 kB Committed_AS: 35876 kB VmallocTotal: 253952 kB VmallocUsed: 4596 kB VmallocChunk: 241660 kB
I think that I make a mistake, but where did I make it?

To recover some of the memory in caches and buffers look at the trick in http://www.timesys.com/blogs/joseph/freememory
