Descriptor objects

cdecl and stdcall are callable Dict descriptors whose public CALL Block returns target-specific calling-convention Text.

Fields

• CALL: a Block that supplies the convention Text when the descriptor is called.
• The returned text is chosen using storageSize of Natx, not the operating-system name.

cdecl

stdcall

Descriptor use

• The same options descriptor is also accepted by codeRef; the convention text becomes part of the resulting Code schema.

Known issue: The convention option is accepted and is part of the Code schema, but it is not emitted in generated LLVM declarations, definitions, or calls. With -32bits, stdcall functions are declared, defined, and called without x86_stdcallcc.

Examples

One descriptor in a callable declaration

"String"      use
"control"     use
"conventions" use

addOne: {value: Int32;} Int32 {convention: cdecl;} codeRef;
[1 +] !addOne

{} Int32 {} [
  ("result=" 41 addOne LF) printList
  0
] "main" exportFunction

Expected Output

result=42
