260 * Build a 16-bit-to-Wine callback glue function.
262 * The generated routines are intended to be used as argument conversion
263 * routines to be called by the CallFrom16... core. Thus, the prototypes of
264 * the generated routines are (see also CallFrom16):
266 * extern WORD WINAPI PREFIX_CallFrom16_C_word_xxx( FARPROC func, LPBYTE args );
267 * extern LONG WINAPI PREFIX_CallFrom16_C_long_xxx( FARPROC func, LPBYTE args );

269 * CONTEXT86 *context );
270 * extern void WINAPI PREFIX_CallFrom16_C_intr_xxx( FARPROC func, LPBYTE args,
271 * CONTEXT86 *context );
273 * where 'C' is the calling convention ('p' for pascal or 'c' for cdecl),
274 * and each 'x' is an argument ('w'=word, 's'=signed word, 'l'=long,
275 * 'p'=linear pointer, 't'=linear pointer to null-terminated string,
276 * 'T'=segmented pointer to null-terminated string).
278 * The generated routines fetch the arguments from the 16-bit stack (pointed
279 * to by 'args'); the offsets of the single argument values are computed
280 * according to the calling convention and the argument types. Then, the
281 * 32-bit entry point is called with these arguments.
283 * For register functions, the arguments (if present) are converted just
284 * the same as for normal functions, but in addition the CONTEXT86 pointer
285 * filled with the current register values is passed to the 32-bit routine.
286 * (An 'intr' interrupt handler routine is treated exactly like a register
287 * routine, except that upon return, the flags word pushed onto the stack
288 * by the interrupt is removed by the 16-bit call stub.)
