83 | /* There are several classifications of routines: | |
84 | ||
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. | |
89 | ||
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. | |
93 | ||
94 | One of the following should be used immediately after the declaration | |
95 | of each symbol: | |
96 | ||
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. | |
101 | ||
102 | export_proto Marks a symbol to be exported, and adds PREFIX | |
103 | to the assembly-level symbol name. | |
104 | ||
105 | export_proto_np Marks a symbol to be exported without adding PREFIX. | |
106 | ||
107 | iexport_proto Marks a function to be exported, but with the | |
108 | understanding that it can be used inside as well. | |
109 | ||
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. | |
114 | ||
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. */ | |
