165 * BuildCallFrom16Func

169 * The generated routines are intended to be used as argument conversion
170 * routines to be called by the CallFrom16... core. Thus, the prototypes of
171 * the generated routines are (see also CallFrom16):
172 *
173 * extern WORD WINAPI PREFIX_CallFrom16_C_word_xxx( FARPROC func, LPBYTE args );
174 * extern LONG WINAPI PREFIX_CallFrom16_C_long_xxx( FARPROC func, LPBYTE args );
175 * extern void WINAPI PREFIX_CallFrom16_C_regs_xxx( FARPROC func, LPBYTE args,
176 * CONTEXT86 *context );
177 *
178 * where 'C' is the calling convention ('p' for pascal or 'c' for cdecl),
179 * and each 'x' is an argument ('w'=word, 's'=signed word, 'l'=long,
180 * 'p'=linear pointer, 't'=linear pointer to null-terminated string,
181 * 'T'=segmented pointer to null-terminated string).
182 *
183 * The generated routines fetch the arguments from the 16-bit stack (pointed
184 * to by 'args'); the offsets of the single argument values are computed
185 * according to the calling convention and the argument types. Then, the
186 * 32-bit entry point is called with these arguments.
187 *
188 * For register functions, the arguments (if present) are converted just
189 * the same as for normal functions, but in addition the CONTEXT86 pointer
190 * filled with the current register values is passed to the 32-bit routine.
