UCS_PTR_BYTE_DIFF(_start, _end)¶

ucs_static_array_size(_array)¶: Size of statically-declared array

ucs_offsetof(_type, _member)¶

Returns: Offset of _member in _type. _type is a structure type.

ucs_container_of(_ptr, _type, _member)¶

Get a pointer to a struct containing a member.

Parameters

_ptr – Pointer to the member.
_type – Container type.
_member – Element member inside the container.

Returns

Address of the container structure.

ucs_typeof(_type)¶

Get the type of a structure or variable.

Parameters

_type – Return the type of this argument.

Returns

The type of the given argument.

ucs_derived_of(_ptr, _type)¶

Returns: Address of a derived structure. It must have a “super” member at offset 0. NOTE: we use the built-in offsetof here because we can’t use ucs_offsetof() in a constant expression.

ucs_field_sizeof(_type, _field)¶

Parameters

_type – Structure type.
_field – Field of structure.

Returns

Size of _field in _type.

ucs_field_type(_type, _field)¶

Parameters

_type – Structure type.
_field – Field of structure.

Returns

Type of _field in _type.

ucs_is_unsigned_type(_type)¶

Parameters

_type – Integer type.

Returns

Whether integer type is unsigned.

ucs_compiler_fence()¶: Prevent compiler from reordering instructions

ucs_prefetch(p)¶: Prefetch cache line
