US Patent 10514904 Dynamically applying a patch to a computer application

Some examples described herein relate to dynamically applying a patch to a computer application. An external process may be invoked to bring a target process of the computer application to a safe point. A dynamic loader may load a patch library into an address space of the target process, wherein the patch library includes a patched version of a target function or a new function. A specific function in the dynamic loader may be directed to route a function call for the target function to the patched version of the target function or the new function in the patch library.
