Hotpatch is a library that can be used to dynamically load a shared library (.so) file on Linux from one process into another already running process without affecting the execution of the target process. The API is a C API, but also supported in C++. The user can load his/her own .so file into an already running process, invoke a custom symbol/function in that .so file, and pass arguments to that function as long as it is serialized to the form of a byte buffer and length of the buffer.
