What does it mean to call a function with one that was int and is passed as (void *) ?
If the variable was declared as int because it is passed as a parameter to a *(void *)variavel* function?
Example
int var = 10;
teste((void *)var);
(void *) means that it is a pointer to a variable not specifying the type of the variable.
For example, you can have the same concept with (int *) where a pointer is to a variable of type int , specifying the type.
Microsoft has a document that explains this a bit in link
