Dynamic Loading of Versioned Libraries

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.
