memexecve is a quick demo to demonstrate execveing an ELF file in memory without ANY disk interaction. This does not serve a practical purpose at all, but is fun regardless.
gcc *.c -o memexecve
./memexecve /path/to/binary arg1 arg2 arg3 ..
Whilst it looks ironic to load a file from disk at first glance, standalone code can be found in memexecve.{c|h}
