DESCRIPTION

src/pmc/managedstruct.pmc - Memory-managed C struct

DESCRIPTION

ManagedStruct extends UnManagedStruct to provide a class to hold C struct values that Parrot is responsible for disposing of.

Methods

void init()

Initializes an empty struct.

void init_pmc(PMC *value)

Initializes the struct with *value.

void destroy()

Destroys the struct, freeing the allocated memory.If the "custom_free_func" attribute is set, it is called to free the pointer. Otherwise, mem_gc_free() is used.

void set_integer_native(INTVAL value)

(Re)allocates value bytes for the struct.

PMC * clone()

Creates a clone of this PMC; clones any unmanaged memory it holds too.If the "custom_clone_func" attribute is set, it is called to clone the PMC. Otherwise, a basic (shallow copy) clone is performed, as there's no general way of knowing how to make a deep copy of the pointer contents.
