ImGuiDestroyContext

ImGuiDestroyContext is a function provided by the Dear ImGui library. Its primary purpose is to deallocate and release all resources that were previously allocated by ImGui when it was initialized. When you create an ImGui context using ImGui::CreateContext, the library reserves memory and sets up various internal data structures. ImGuiDestroyContext is the counterpart to this initialization process. Calling it signifies that you are finished with Dear ImGui for the current application or session and wish to free up the associated memory.

It is crucial to call ImGuiDestroyContext before your application exits or when you no longer need ImGui to prevent memory leaks. Failure to do so can lead to a portion of your program's memory remaining allocated even after the application has terminated, potentially impacting system stability or the availability of memory for other processes. The function takes no arguments and returns void. It should be called only once after all ImGui drawing commands have been issued and typically just before the main application loop terminates.
