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 *
321 * where 'C' is the calling convention ('p' for pascal or 'c' for cdecl),
322 * and each 'x' is an argument ('w'=word, 's'=signed word, 'l'=long,
323 * 'p'=linear pointer, 't'=linear pointer to null-terminated string,
324 * 'T'=segmented pointer to null-terminated string).
325 *
326 * The generated routines fetch the arguments from the 16-bit stack (pointed
327 * to by 'args'); the offsets of the single argument values are computed
328 * according to the calling convention and the argument types. Then, the
329 * 32-bit entry point is called with these arguments.
330 *
331 * For register functions, the arguments (if present) are converted just
332 * the same as for normal functions, but in addition the CONTEXT86 pointer
333 * filled with the current register values is passed to the 32-bit routine.
