Why compiler says error: no spread elements allowed here for this code?

immutableBinaryBlobOf(*(name.toCharArray() as ShortArray))

[svyatoslav.scherbina]

Because spread operator * is not allowed in immutableBinaryBlobOf. The latter must be evaluated in compile time, and having * among arguments complicates this.

[Andrey Gromov]

Okay... Maybe you advise me the best way to create immutableBinaryBlobOf from compile time String constant?

[svyatoslav.scherbina]

I’m not sure it is possible currently.
Why do you need this?

[rjhdby]

See question above. Mike Sinkovsky gave advice about forwarding args as compile-time constant for using in macro

[svyatoslav.scherbina]

If I understand correctly, it appeared to be unrelated: https://kotlinlang.slack.com/archives/C3SGXARS6/p1533647735000300?thread_ts=1533629726.000018&cid=C3SGXARS6

It doesn’t matter for C wrapper whether you pass stable pointer to constant string or not, because sizeof(name) would be incorrect there in any case, since name expands to arg which is parameter of type char*.
