In addition, the stack_size argument can be 0, in which case the operating system uses the same value as the stack that's specified for the main thread.

Edit: So if i dont use void, it seems i have to write lot of calc "identical" function for each type....

Do i have to use calloc/realloc for the int too ? like i used it for the char/struct array.

So please can you show me the right way to cast correctly
