PmReturn_t class_getAttr	(	pPmObj_t	pobj,
		pPmObj_t	pname,
		pPmObj_t *	r_pobj
	)

Returns the first attribute named __init__ in the class' inheritance tree

Parameters:

	pobj	ptr to class or instance to search
	pname	ptr to name of attr to find
	r_pobj	Return by ref, ptr to attr if found, or undetermined

Returns:

Return status

PmReturn_t class_instantiate	(	pPmObj_t	pclass,
		pPmObj_t *	r_pobj
	)

Returns an instance of the given class

Parameters:

r_pobj

The class object as input, instance object as return

Returns:

Return status

uint8_t class_isSubclass	(	pPmObj_t	ptest_class,
		pPmObj_t	pbase_class
	)

Returns a C boolean if the base class is found in the inheritance tree of the test class. NOTE: This function is recursive.

Parameters:

	ptest_class	ptr to class whose inheritance tree is searched
	pbase_class	ptr to class to look for

Returns:

Returns C_TRUE if pbase_class is found in the inheritance tree; C_FALSE otherwise.

PmReturn_t class_method	(	pPmObj_t	pinstance,
		pPmObj_t	pfunc,
		pPmObj_t *	r_pmeth
	)

Returns a method based on the given inputs

Parameters:

	pinstance	ptr to instance
	pfunc	ptr to func
	r_pmeth	Return by ref, ptr to new method

Returns:

Return status

PmReturn_t class_new	(	pPmObj_t	pmeths,
		pPmObj_t	pbases,
		pPmObj_t	pname,
		pPmObj_t *	r_pclass
	)

Creates a new Class object from the methods dict, bases tuple, and name string.

Parameters:

	pmeths	ptr to methods dict.
	pbases	ptr to bases tuple.
	pname	ptr to name string.
	r_pclass	Return by ref, ptr to new class

Returns:

Return status
