C Code

You can include any C code you would like inside of a block, like this:

--c--
printf("Hello from C");
--c--

To make it easy to inter-operate with SJ, there are several macros you can use in your C code:

--c--
#include(<stdio.h>) // Add an include statement to output, include statements are sorted alphabetically and only included once
#type(i32) // Converts an SJ type into the C equivalent
#retain(x) // Keeps a reference to an object, this is required if you are keeping a value beyond the scope of this request
#release(x) // Drop your reference
#isValue(i32) // Returns true if type is a simple value and false if type is function pointer	
--c--

In C you may also need to access an SJ variable:

class(
    y : 0
    func(x : 0) {
        result := 0
        --c--
        result = x + _parent->y;
        --c--
    }
) {
    --c--
    _this->y = 1234;
    --c--
    this 
}
