I don't think ptr needs to be re-casted to void because eventhough we casted it to char, it's still a void pointer, isn't it?<br />
<br />
Example:<br />
<br />
void somefunc(void * some_ptr);<br />
<br />
void * ptr;<br />
char * some_ptr;<br />
<br />
some_ptr = ((char *)ptr)++;<br />
<br />
/* I shouldn't need to recast ptr to void before passing it as an argument to a function */<br />
somefunc(ptr); &nbsp; &nbsp; /* will this work? */<br />

I don't think ptr needs to be re-casted to void because eventhough we casted it to char, it's still a void pointer, isn't it?

Example:

void somefunc(void * some_ptr);

void * ptr;
char * some_ptr;

some_ptr = ((char *)ptr)++;

/* I shouldn't need to recast ptr to void before passing it as an argument to a function */
somefunc(ptr);     /* will this work? */

void * ptr;
Can ptr be casted to pointer to char.  Then, can it be re-casted to pointer to void?



Can void pointer be casted to char and then re-casted to void?

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
