97 (1) Symbols used only within the library,
98 (2) Symbols to be exported from the library,
99 (3) Symbols to be exported from the library, but
100 also used inside the library.
102 By telling the compiler about these different classifications we can
103 tightly control the interface seen by the user, and get better code
104 from the compiler at the same time.
106 One of the following should be used immediately after the declaration
109 internal_proto Marks a symbol used only within the library,
110 and adds IPREFIX to the assembly-level symbol
111 name. The later is important for maintaining
112 the namespace partition for the static library.
114 export_proto Marks a symbol to be exported, and adds PREFIX
115 to the assembly-level symbol name.
117 export_proto_np Marks a symbol to be exported without adding PREFIX.
119 iexport_proto Marks a function to be exported, but with the
120 understanding that it can be used inside as well.
122 iexport_data_proto Similarly, marks a data symbol to be exported.
123 Unfortunately, some systems can't play the hidden
124 symbol renaming trick on data symbols, thanks to
125 the horribleness of COPY relocations.
127 If iexport_proto or iexport_data_proto is used, you must also use
128 iexport or iexport_data after the *definition* of the symbol. */
