+All Global Variables and Functions have one of the following visibility styles:

+
+<dl>
+ <dt><b>"<tt>default</tt>" - Default style</b>:</dt>
+
+ <dd>On ELF, default visibility means that the declaration is visible to other
+ modules and, in shared libraries, means that the declared entity may be
+ overridden. On Darwin, default visibility means that the declaration is
+ visible to other modules. Default visibility corresponds to "external
+ linkage" in the language.
+ </dd>
+
+ <dt><b>"<tt>hidden</tt>" - Hidden style</b>:</dt>
+
+ <dd>Two declarations of an object with hidden visibility refer to the same
+ object if they are in the same shared object. Usually, hidden visibility
+ indicates that the symbol will not be placed into the dynamic symbol table,
+ so no other module (executable or shared library) can reference it
+ directly.
