void SCardUnload ( void   ) 

free resources allocated by the library You _shall_ call this function if you use dlopen/dlclose to load/unload the library. Otherwise you will exhaust the ressources available.

Definition at line 1896 of file winscard_scf.c.

       *    Cleanup only if PCSC has been initialized and there are no active
       *    context.  Checking for active context is critical when libpcsclite is
       *    linked with multiple modules. for eg. an application links with
       *    pcsclite and a PAM module also links with pcsclite, when the PAM is
       *    unloaded from memory and if it calls SCardUnload, pcsclite will
       *    un-initialize even though there are active references from the
       *    application. Now, why dont we add SCardUnload to the array of functions
       *    to be called on unload (-zfiniarray=SCUnload), well, that does not seem
       *    to solve the problem, SCardUnload is called when PAM is unloaded from
       *    memory having the same impact that PCSC is uninitialized enen though
       *    there are active references.
