hi , 
&nbsp; &nbsp; &nbsp; &nbsp;I &nbsp;have an &nbsp;IDL file .I want &nbsp;to know &nbsp;how &nbsp;to

The MIDL compiler ignores &nbsp;this &nbsp;declaration &nbsp;. 
 
Here Save Method accepts a &nbsp;file pointer and also &nbsp; 
a function pointer as an argument .However when I declared 
it this way , the MIDL compiler ignored it . 
 
I want &nbsp;to &nbsp;know &nbsp;how &nbsp;to &nbsp;declare it &nbsp;so &nbsp;that &nbsp;the

hi ,
       I  have an  IDL file .I want  to know  how  to 
declare  a  function pointer  as a  function argument in
the IDL file  .
 
when I declared it like -->

   int Save([in] FILE *fp , unsigned int (*pFn)(const void *buffer, size_t size, size_t count, FILE *stream));	

The MIDL compiler ignores  this  declaration  .

Here Save Method accepts a  file pointer and also  
a function pointer as an argument .However when I declared
it this way , the MIDL compiler ignored it .

I want  to  know  how  to  declare it  so  that  the
MIDL compiler accepts  it  .

If  you have any clue  to this  problem , please
