Struct R_CallMethodDef

Source

#[repr(C)]pub struct R_CallMethodDef {
    pub name: *const c_char,
    pub fun: DL_FUNC,
    pub numArgs: c_int,
}

Expand description

Method definition for .Call interface routines.

Used to register C functions callable via .Call() from R. Unlike .C() routines, .Call() functions receive and return SEXP values directly.

Fields§

§name: *const c_char

Exported symbol name.

§fun: DL_FUNC

Function pointer implementing the routine.

§numArgs: c_int

Declared arity.
