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