* extern void WINAPI __wine_spec_call16_C_xxx_regs( 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.
