Creating and Using Libraries

Version Control with Shared Libraries

With these links in place, the loader will load /X/libapp.0 when

 

running the a.out file created above. New applications will link and run

 

with /X/libapp.1.

 

Renaming the old version of the .0 version library only works for 32-bit

mode.

 

For 64-bit mode programs, the dynamic loader only loads the library

 

 

recorded in the dynamic load table. You should use library-lever

 

versioning and create your 64-bit shared library with an internal name

 

unless the library will not be versioned in the future.

Using shl_load(3X) with Library-Level Versioning

Once library level versioning is used, calls to shl_load(3X) should specify the actual version of the library to be loaded. For example, if libA.sl is now a symbolic link to libA.1, then calls to dynamically load this library should specify the latest version available when the application is compiled as shown below:

shl_load("libA.1", BIND_DEFERRED, 0);

This insures that when the application is migrated to a system that has a later version of libA available, the actual version desired is the one that is dynamically loaded.

Intra-Library Versioning

Intra-library versioning is a second method of maintaining multiple incompatible versions of shared library routines. Library-level versioning is recommended over intra-library versioning.
