| * the generated routines are (see also CallFrom16): | |
| * | |
| * extern WORD WINAPI PREFIX_CallFrom16_C_word_xxx( FARPROC func, LPBYTE args ); | |
| * extern LONG WINAPI PREFIX_CallFrom16_C_long_xxx( FARPROC func, LPBYTE args ); | |

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