308 * BuildCallFrom16Func
309 *
310 * Build a 16-bit-to-Wine callback glue function.
311 *
312 * The generated routines are intended to be used as argument conversion
313 * routines to be called by the CallFrom16... core. Thus, the prototypes of
314 * the generated routines are (see also CallFrom16):
315 *
316 * extern WORD WINAPI PREFIX_CallFrom16_C_word_xxx( FARPROC func, LPBYTE args );
317 * extern LONG WINAPI PREFIX_CallFrom16_C_long_xxx( FARPROC func, LPBYTE args );
318 * extern void WINAPI PREFIX_CallFrom16_C_regs_xxx( FARPROC func, LPBYTE args,
319 * CONTEXT86 *context );
320 * extern void WINAPI PREFIX_CallFrom16_C_intr_xxx( FARPROC func, LPBYTE args,
321 * CONTEXT86 *context );
322 *
323 * where 'C' is the calling convention ('p' for pascal or 'c' for cdecl),
324 * and each 'x' is an argument ('w'=word, 's'=signed word, 'l'=long,
325 * 'p'=linear pointer, 't'=linear pointer to null-terminated string,
326 * 'T'=segmented pointer to null-terminated string).
327 *
328 * The generated routines fetch the arguments from the 16-bit stack (pointed
329 * to by 'args'); the offsets of the single argument values are computed
330 * according to the calling convention and the argument types. Then, the
331 * 32-bit entry point is called with these arguments.
332 *
333 * For register functions, the arguments (if present) are converted just
334 * the same as for normal functions, but in addition the CONTEXT86 pointer
335 * filled with the current register values is passed to the 32-bit routine.
336 * (An 'intr' interrupt handler routine is treated exactly like a register
337 * routine, except that upon return, the flags word pushed onto the stack
338 * by the interrupt is removed by the 16-bit call stub.)
