     19 Parameter
     20 ~~~~~~~~~
     21 
     22 :ref:`PR_VersionCheck` has one parameter:
     23 
     24 ``importedVersion``
     25   The version of the shared library being imported.

     29 ~~~~~~~
     30 
     31 The function returns one of the following values:
     32 
     33 -  If the version of the shared library is compatible with that expected
     34   by the caller, ``PR_TRUE``.
     35 -  If the versions are not compatible, ``PR_FALSE``.

     38 Description
     39 -----------
     40 
     41 :ref:`PR_VersionCheck` tests whether the version of the library being
     42 imported (``importedVersion``) is compatible with the running version of
     43 the shared library. This is a string comparison of sorts, though the
     44 details of the comparison will vary over time.
