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