Is there any way to easily limit a C/C++ application to a specified amount of memory (30 mb or so)? Eg: if my application tries to complete load a 50mb file into memory it will die/print a message and quit/etc.
Admittedly I can just constantly check the memory usage for the application, but it would be a bit easier if it would just die with an error if I went above.
Any ideas?
Platform isn’t a big issue, windows/linux/whatever compiler.
Read the manual page for
ulimiton unix systems. There is a shell builtin you can invoke before launching your executable or (in section 3 of the manual) an API call of the same name.
