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