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