Ok cool, I get it. So Nim's default is to pass objects to procs via reference,
right? So if I wanted to do that, while keeping the original C function names
and only using pass-by-value value when calling them, would this be ok?
type
OriginalMyStruct* {.bycopy.} = object
id*: cuint
width*: cfloat
height*: cfloat
mipmaps*: cint
format*: cint
MyStruct = ref OriginalMyStruct
proc OriginalPrintStructValues(testStruct: OriginalMyStruct)
{.cdecl, importc: "PrintStructValues", dynlib: "./struct_test.so".}
template PrintStructValues*(testStruct: MyStruct) =
OriginalPrintStructValues(testStruct[])
var testStruct = MyStruct(
id: 1,
width: 2.0,
height: 3.0,
mipmaps: 4,
format: 5
)
PrintStructValues(testStruct)
I've tested it and it works. Is there a better way of doing it?
