158 (1) Symbols used only within the library,
159 (2) Symbols to be exported from the library,
160 (3) Symbols to be exported from the library, but
161 also used inside the library.
162
163 By telling the compiler about these different classifications we can
164 tightly control the interface seen by the user, and get better code
165 from the compiler at the same time.
166
167 One of the following should be used immediately after the declaration
168 of each symbol:
169
170 internal_proto Marks a symbol used only within the library,
171 and adds IPREFIX to the assembly-level symbol
172 name. The later is important for maintaining
173 the namespace partition for the static library.
174
175 export_proto Marks a symbol to be exported, and adds PREFIX
176 to the assembly-level symbol name.
177
178 export_proto_np Marks a symbol to be exported without adding PREFIX.
179
180 iexport_proto Marks a function to be exported, but with the
181 understanding that it can be used inside as well.
182
183 iexport_data_proto Similarly, marks a data symbol to be exported.
184 Unfortunately, some systems can't play the hidden
185 symbol renaming trick on data symbols, thanks to
186 the horribleness of COPY relocations.
187
188 If iexport_proto or iexport_data_proto is used, you must also use
189 iexport or iexport_data after the *definition* of the symbol. */
