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