69 | /* THE JUMPTABLE FUNCTIONS. |
| 70 | ||
| 71 | * The _IO_FILE type is used to implement the FILE type in GNU libc, | |
| 72 | * as well as the streambuf class in GNU iostreams for C++. | |
| 73 | * These are all the same, just used differently. | |
| 74 | * An _IO_FILE (or FILE) object is allows followed by a pointer to | |
| 75 | * a jump table (of pointers to functions). The pointer is accessed | |
| 76 | * with the _IO_JUMPS macro. The jump table has a eccentric format, | |
| 77 | * so as to be compatible with the layout of a C++ virtual function table. | |
| 6d52618b | 78 | * (as implemented by g++). When a pointer to a streambuf object is |
| f65fd747 UD |
79 | * coerced to an (_IO_FILE*), then _IO_JUMPS on the result just |
| 80 | * happens to point to the virtual function table of the streambuf. | |
| 81 | * Thus the _IO_JUMPS function table used for C stdio/libio does | |
| 6d52618b | 82 | * double duty as the virtual function table for C++ streambuf. |
| f65fd747 UD |
83 | * |
| 84 | * The entries in the _IO_JUMPS function table (and hence also the | |
| 85 | * virtual functions of a streambuf) are described below. | |
| 86 | * The first parameter of each function entry is the _IO_FILE/streambuf | |
| 87 | * object being acted on (i.e. the 'this' parameter). | |
