Questions tagged [dynamic-library]

Compiled binaries capable to be loaded in the process address space in runtime.

Dynamic Libraries are compiled binaries capable of being loaded/unloaded into/from the process address space at runtime.

In the Unix world, they are called shared libraies; in the Windows world, they are known as DLLs (dynamically-loadable libraries).

They can be loaded simultaneously into multiple processes, saving RAM and disk space.

Their file format is similar to, or even the same as, that of binary executables.
