VFVM has first-class support for plugins.
As of now, there is only one- partial match output, which prints progressively longer prefix matches as the target address is mined.
Please see examples for a simple example that just adds some logging.
To run an example, copy its directory into plugins/ before compiling with make PLUGINS=true
Allocating memory is slow, and therefor ought only be done on a plugin's on_init or constructor-attribute path.
Any allocated memory must be released in the destructor-attribute path, the plugin will not be accepted.
Note that VFVM uses pthreads to scale.
This means that on_iteration is called concurrently, and must therefor be thread-safe.
Incidentally, because on_iteration is called concurrently, on_progress must not access memory in an unsafe manner.
