Difference between load-time and run-time dynamic linking

Question

What is the difference between Load-time dynamic linking and Run-time dynamic linking?

Answer 1

Load time dynamic linking is performed by Operating System when an application is loaded. OS uses the information linker has placed in the file to locate the names of the dll, and then searches for those dlls, And if it fails to locate the Dll, it simply terminates and gives error message, otherwise, OS maps the DLL into the virtual address space of the process and increases the DLL reference count.
