XDCscript - Struct-Object.$sizeof

The target size of a structure

Synopsis

«tobj».$sizeof()

Description

Returns the target size of the structure «tobj» in target chars. In other words, this function returns the same value that the target compiler would provide when applying the C sizeof() operator on the structure. Note this may be different from the number of 8-bit bytes in the structure; some target architectures have a 16-bit char.

Example

The following example illustrates the use of the $sizeof() method. The size of the structure declared in Mod.xdc is printed from an application configuration script app.cfg.

module Mod { 
    struct S = {
        Int x;
        Char c;
    }
}

var Mod = xdc.useModule("Mod");
print("sizeof Mod.S = " + Mod.S.$sizeof());
