Call

Call any function at an address using the x64 calling convention.

Syntax

Susano.Memory.Call(address, signature, ...) -> ...

Parameters

address (integer): Function address.

signature (string): Format is "<return>:<args>" where each character is a type:

v: void
i: int32
l: int64 / long
b: bool
f: float
d: double
p: pointer (integer, nil is treated as 0)
s: string (const char*)

The character before : is the return type, the characters after : are the argument types (maximum 16 args).

... : Argument values matching the signature types.

Return(s)

Depends on the return type in the signature. void returns nothing.

Example(s)

-- void func(int, int)
Susano.Memory.Call(addr, "v:ii", 1, 2)

-- int64 func(pointer, int)
local result = Susano.Memory.Call(addr, "l:pi", entityPtr, 42)

-- float func(float, float)
local dist = Susano.Memory.Call(addr, "f:ff", 1.0, 2.0)

-- no-arg function returning int64
local tick = Susano.Memory.Call(tickProc, "l:")

-- pointer func(string)
local ret = Susano.Memory.Call(addr, "p:s", "hello")
