Detailed Description

Internal definition of a reverse trampoline (callback/closure) handle.

This is the concrete implementation of the opaque infix_reverse_t pointer. The entire struct is allocated in a page-aligned memory region that is made read-only after initialization to prevent memory corruption vulnerabilities. Like the forward trampoline, it is self-contained and owns deep copies of all its type metadata.

Member Data Documentation

arena

infix_arena_t* infix_reverse_t::arena

Private arena for type metadata.

arg_types

infix_type** infix_reverse_t::arg_types

Deep copy of the function's argument types.

cached_forward_trampoline

infix_forward_t* infix_reverse_t::cached_forward_trampoline

For type-safe callbacks, a pre-generated trampoline to call the C handler.

exec

infix_executable_t infix_reverse_t::exec

Executable memory for the JIT stub.

internal_dispatcher

infix_internal_dispatch_callback_fn infix_reverse_t::internal_dispatcher

Pointer to the universal C dispatcher implementation.

is_variadic

bool infix_reverse_t::is_variadic

true if the signature contains variadic arguments.

num_args

size_t infix_reverse_t::num_args

Total number of arguments.

num_fixed_args

size_t infix_reverse_t::num_fixed_args

Number of non-variadic arguments.

protected_ctx

infix_protected_t infix_reverse_t::protected_ctx

The read-only memory region holding this struct.

return_type

infix_type* infix_reverse_t::return_type

Deep copy of the function's return type.

user_callback_fn

void* infix_reverse_t::user_callback_fn

The user-provided handler function pointer (type-safe or generic).

user_data

void* infix_reverse_t::user_data

The user-provided context pointer for closures.
