/* 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 a 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).
