290 * BuildCallFrom16Func
291 *
292 * Build a 16-bit-to-Wine callback glue function.
293 *
294 * The generated routines are intended to be used as argument conversion
295 * routines to be called by the CallFrom16... core. Thus, the prototypes of
296 * the generated routines are (see also CallFrom16):
297 *
298 * extern WORD WINAPI PREFIX_CallFrom16_C_word_xxx( FARPROC func, LPBYTE args );
299 * extern LONG WINAPI PREFIX_CallFrom16_C_long_xxx( FARPROC func, LPBYTE args );
300 * extern void WINAPI PREFIX_CallFrom16_C_regs_xxx( FARPROC func, LPBYTE args,
301 * CONTEXT86 *context );
302 * extern void WINAPI PREFIX_CallFrom16_C_intr_xxx( FARPROC func, LPBYTE args,
303 * CONTEXT86 *context );
304 *
305 * where 'C' is the calling convention ('p' for pascal or 'c' for cdecl),
306 * and each 'x' is an argument ('w'=word, 's'=signed word, 'l'=long,
307 * 'p'=linear pointer, 't'=linear pointer to null-terminated string,
308 * 'T'=segmented pointer to null-terminated string).
309 *
310 * The generated routines fetch the arguments from the 16-bit stack (pointed
311 * to by 'args'); the offsets of the single argument values are computed
312 * according to the calling convention and the argument types. Then, the
313 * 32-bit entry point is called with these arguments.
314 *
315 * For register functions, the arguments (if present) are converted just
316 * the same as for normal functions, but in addition the CONTEXT86 pointer
317 * filled with the current register values is passed to the 32-bit routine.
318 * (An 'intr' interrupt handler routine is treated exactly like a register
319 * routine, except that upon return, the flags word pushed onto the stack
320 * by the interrupt is removed by the 16-bit call stub.)
