void module_get_imported_function_module_and_name(const Module *this_module, int index, AtomString *module_atom, AtomString *function_atom, GlobalContext *glb)

Gets imported function module and name.

Gets imported function module and name given its import table index.

Parameters:

• this_module – the module on which the function will be searched.

• index – the modules import table offset to begin searching.

• module_atom – module name atom string.

• function_atom – function name atom string.

bool module_get_function_from_label(Module *this_module, int label, AtomString *function_name, int *arity, GlobalContext *glb)

size_t module_get_exported_functions_count(Module *this_module)

Count exported functions of a given module.

Get the number of exported functions. This function is used to compute the required heap size of the list of exported functions.

Parameters:

• this_module – the module to count exported functions of

Returns:

the number of exported functions

uint32_t module_search_exported_function(Module *this_module, AtomString func_name, int func_arity, GlobalContext *glb)

Gets exported function index by searching it by function name and arity.

Gets exported function index by searching it by function name and arity

Parameters:

• this_module – the module on which the function will be searched.

• func_name – function name atom string.

• func_arity – function arity.

• glb – the global context

term module_get_exported_functions(Module *this_module, Heap *heap, GlobalContext *glb)

Get the list of exported functions.

Create a list of exported functions of the form {FunctionName, Arity} To create this list, the heap must be grown by module_get_exported_functions_list_size terms.

Parameters:

• this_module – the module to count exported functions of

• heap – heap to allocate tuples

• global – global context to fetch atoms

Returns:

a list of exported functions

Module *module_new_from_iff_binary(GlobalContext *global, const void *iff_binary, unsigned long size)

Parse a BEAM file and returns a Module.

Parse a BEAM file a returns a newly allocated and initialized Module struct.

Parameters:

• global – the global context.

• iff_binary – the IFF file data.

• size – the size of the buffer containing the IFF data.

void module_destroy(Module *module)

term module_load_literal(Module *mod, int index, Context *ctx)

Gets a literal stored on the literal table of the specified module.

Loads and deserialize a term stored in the literal table and returns a term.

Parameters:

• mod – The module that owns that is going to be loaded.

• index – a valid literal index.

• ctx – the target context.
