Typedef Documentation

MR_std_optional_double

typedef struct MR_std_optional_double MR_std_optional_double

Stores either a single double or nothing. Supported MR_PassBy modes: MR_PassBy_DefaultConstruct, MR_PassBy_Copy, MR_PassBy_Move, (and MR_PassBy_DefaultArgument and MR_PassBy_NoObject if supported by the callee).

Function Documentation

MR_std_optional_double_AssignFrom()

MRC_API void MR_std_optional_double_AssignFrom	(	MR_std_optional_double *	_this,
		const double *	other )

Assigns the contents. Parameter _this can not be null. It is a single object. Parameter other is optional. To keep it empty, pass a null pointer.

MR_std_optional_double_AssignFromAnother()

MRC_API void MR_std_optional_double_AssignFromAnother	(	MR_std_optional_double *	_this,
		const MR_std_optional_double *	other )

Assigns the contents from another instance. Both objects remain alive after the call. Parameter _this can not be null. It is a single object. Parameter other can not be null. It is a single object.

MR_std_optional_double_ConstructFrom()

MRC_API MR_std_optional_double * MR_std_optional_double_ConstructFrom

(

const double *

other

)

Constructs a new instance. Parameter other is optional. To keep it empty, pass a null pointer. Never returns null. Returns an instance allocated on the heap! Must call MR_std_optional_double_Destroy() to free it when you're done using it.

MR_std_optional_double_ConstructFromAnother()

MRC_API MR_std_optional_double * MR_std_optional_double_ConstructFromAnother

(

const MR_std_optional_double *

other

)

Constructs a copy of another instance. The source remains alive. Parameter other can not be null. It is a single object. Never returns null. Returns an instance allocated on the heap! Must call MR_std_optional_double_Destroy() to free it when you're done using it.

MR_std_optional_double_DefaultConstruct()

MRC_API MR_std_optional_double * MR_std_optional_double_DefaultConstruct

(

void

)

Constructs an empty (default-constructed) instance. Never returns null. Returns an instance allocated on the heap! Must call MR_std_optional_double_Destroy() to free it when you're done using it.

MR_std_optional_double_DefaultConstructArray()

MRC_API MR_std_optional_double * MR_std_optional_double_DefaultConstructArray

(

size_t

num_elems

)

Constructs an array of empty (default-constructed) instances, of the specified size. Will never return null. The array must be destroyed using MR_std_optional_double_DestroyArray(). Use MR_std_optional_double_OffsetMutablePtr() and MR_std_optional_double_OffsetPtr() to access the array elements.

MR_std_optional_double_Destroy()

MRC_API void MR_std_optional_double_Destroy

(

const MR_std_optional_double *

_this

)

Destroys a heap-allocated instance of MR_std_optional_double. Does nothing if the pointer is null.

MR_std_optional_double_DestroyArray()

MRC_API void MR_std_optional_double_DestroyArray

(

const MR_std_optional_double *

_this

)

Destroys a heap-allocated array of MR_std_optional_double. Does nothing if the pointer is null.

MR_std_optional_double_MutableValue()

MRC_API double * MR_std_optional_double_MutableValue

(

MR_std_optional_double *

_this

)

The stored element or null if none, mutable. Parameter _this can not be null. It is a single object.

MR_std_optional_double_OffsetMutablePtr()

MRC_API MR_std_optional_double * MR_std_optional_double_OffsetMutablePtr	(	MR_std_optional_double *	ptr,
		ptrdiff_t	i )

Offsets a pointer to an array element by i positions (not bytes). Use only if you're certain that the pointer points to an array element.

MR_std_optional_double_OffsetPtr()

MRC_API const MR_std_optional_double * MR_std_optional_double_OffsetPtr	(	const MR_std_optional_double *	ptr,
		ptrdiff_t	i )

Offsets a pointer to an array element by i positions (not bytes). Use only if you're certain that the pointer points to an array element.

MR_std_optional_double_Value()

MRC_API const double * MR_std_optional_double_Value

(

const MR_std_optional_double *

_this

)

The stored element or null if none, read-only. Parameter _this can not be null. It is a single object.
