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