| 30 | * This file describes the link editor defined symbols. The semantics of a␊ |
| 31 | * link editor symbol is that it is defined by the link editor only if it is␊ |
| 32 | * referenced and it is an error for the user to define them (see the man page␊ |
| 33 | * ld(1)). The standard UNIX link editor symbols: __end, __etext and __edata␊ |
| 34 | * are not not supported by the Apple Mach-O link editor. These symbols are␊ |
| 35 | * really not meaningful in a Mach-O object file and the link editor symbols␊ |
| 36 | * that are supported (described here) replace them. In the case of the␊ |
| 37 | * standard UNIX link editor symbols the program can use the symbol␊ |
| 38 | * __mh_execute_header and walk the load commands of it's program to determine␊ |
| 39 | * the ending (or beginning) of any section or segment in the program. Note␊ |
| 40 | * that the compiler prepends an underbar to all external symbol names coded␊ |
| 41 | * in a high level language. Thus in 'C' names are coded without an underbar␊ |
| 42 | * and symbol names in the symbol table have an underbar. There are two cpp␊ |
| 43 | * macros for each link editor defined name in this file. The macro with a␊ |
| 44 | * leading underbar is the symbol name and the one without is the name as␊ |
| 45 | * coded in 'C'.␊ |
