Hello,

according to the manual, sizeof() can not be used in expressions (stated on the page about structs).

However, a user has pointed out that sizeof() works in expressions, when a typecast to int is used:
malloc((int)sizeof(datatype) * n)

I would like to know, how save this method is.
At a first glance this workaround does the job fine (and its just written less verbosely).

The method is safe as far as I can see. The (int) converts the definition to a temporary variable, which can then be used in expressions.

We intend to make the sizeof() anyway a real function in one of the next updates, because otherwise it's a potential source of bugs.

All right, thank you!
