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