283 * The generated routines are intended to be used as argument conversion
284 * routines to be called by the CallFrom16... core. Thus, the prototypes of
285 * the generated routines are (see also CallFrom16):
286 *
287 * extern WORD WINAPI PREFIX_CallFrom16_C_word_xxx( FARPROC func, LPBYTE args );
288 * extern LONG WINAPI PREFIX_CallFrom16_C_long_xxx( FARPROC func, LPBYTE args );
289 * extern void WINAPI PREFIX_CallFrom16_C_regs_xxx( FARPROC func, LPBYTE args,
290 * CONTEXT86 *context );
291 * extern void WINAPI PREFIX_CallFrom16_C_intr_xxx( FARPROC func, LPBYTE args,
292 * CONTEXT86 *context );
293 *
294 * where 'C' is the calling convention ('p' for pascal or 'c' for cdecl),
295 * and each 'x' is an argument ('w'=word, 's'=signed word, 'l'=long,
296 * 'p'=linear pointer, 't'=linear pointer to null-terminated string,
297 * 'T'=segmented pointer to null-terminated string).
298 *
299 * The generated routines fetch the arguments from the 16-bit stack (pointed
300 * to by 'args'); the offsets of the single argument values are computed
301 * according to the calling convention and the argument types. Then, the
302 * 32-bit entry point is called with these arguments.
303 *
304 * For register functions, the arguments (if present) are converted just
305 * the same as for normal functions, but in addition the CONTEXT86 pointer
306 * filled with the current register values is passed to the 32-bit routine.
307 * (An 'intr' interrupt handler routine is treated exactly like a register
308 * routine, except that upon return, the flags word pushed onto the stack
309 * by the interrupt is removed by the 16-bit call stub.)
