255 *
256 * The generated routines are intended to be used as argument conversion
257 * routines to be called by the CallFrom16... core. Thus, the prototypes of
258 * the generated routines are (see also CallFrom16):
259 *
260 * extern WORD WINAPI PREFIX_CallFrom16_C_word_xxx( FARPROC func, LPBYTE args );
261 * extern LONG WINAPI PREFIX_CallFrom16_C_long_xxx( FARPROC func, LPBYTE args );
262 * extern void WINAPI PREFIX_CallFrom16_C_regs_xxx( FARPROC func, LPBYTE args,
263 * CONTEXT86 *context );
264 * extern void WINAPI PREFIX_CallFrom16_C_intr_xxx( FARPROC func, LPBYTE args,
265 * CONTEXT86 *context );
266 *
267 * where 'C' is the calling convention ('p' for pascal or 'c' for cdecl),
268 * and each 'x' is an argument ('w'=word, 's'=signed word, 'l'=long,
269 * 'p'=linear pointer, 't'=linear pointer to null-terminated string,
270 * 'T'=segmented pointer to null-terminated string).
271 *
272 * The generated routines fetch the arguments from the 16-bit stack (pointed
273 * to by 'args'); the offsets of the single argument values are computed
274 * according to the calling convention and the argument types. Then, the
275 * 32-bit entry point is called with these arguments.
276 *
277 * For register functions, the arguments (if present) are converted just
278 * the same as for normal functions, but in addition the CONTEXT86 pointer
279 * filled with the current register values is passed to the 32-bit routine.
280 * (An 'intr' interrupt handler routine is treated exactly like a register
281 * routine, except that upon return, the flags word pushed onto the stack
282 * by the interrupt is removed by the 16-bit call stub.)
