When developing an application that dynamically loads versioned libraries, the name used for loading a library requires special attention. Applications should not dynamically load versioned libraries with names of the form library_name.sl. Names ending in the .sl extension are generally associated with symbolic links to one of several possible versions of a library. Although these links are installed in the development environment, they are not typically present in the run-time environment.

To ensure the correct version of a library is loaded, use the name that includes the version extension of the library executable. Use the file name referenced by the libA.sl symbolic link for the library in question. For example, if libA.sl is a symbolic link to libA.1, then use libA.1 for dynamic loading.
