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