Word description
Invokes a C function pointer passed on the data stack. Input parameters are taken from the data stack following the function pointer, and the return value is pushed on the data stack after the function returns. A return type of void indicates that no value is to be expected.

C type names are documented in C type specifiers.

Throws an callsite-not-compiled if the word calling alien-indirect is not compiled.
