Fit aligned storage in buffer.
This function tries to fit __size bytes of storage with alignment __align into the buffer __ptr of size __space bytes. If such a buffer fits then __ptr is changed to point to the first byte of the aligned storage and __space is reduced by the bytes used for alignment.
C++11 20.6.5 [ptr.align]
- Parameters
-
__align | A fundamental or extended alignment value. |
__size | Size of the aligned storage required. |
__ptr | Pointer to a buffer of __space bytes. |
__space | Size of the buffer pointed to by __ptr. |
- Returns
- the updated pointer if the aligned storage fits, otherwise nullptr.

◆ uninitialized_copy()
◆ uninitialized_copy_n()
Copies the range [first,first+n) into result.
- Parameters
-
__first | An input iterator. |
__n | The number of elements to copy. |
__result | An output iterator. |
- Returns
- __result + __n
Like copy_n(), but does not require an initialized output range.

◆ uninitialized_default_construct()
Default-initializes objects in the range [first,last).
- Parameters
-
__first | A forward iterator. |
__last | A forward iterator. |
Definition at line 900 of file stl_uninitialized.h.
◆ uninitialized_default_construct_n()
Default-initializes objects in the range [first,first+count).
- Parameters
-
__first | A forward iterator. |
__count | The number of objects to construct. |
- Returns
- __first + __count

◆ uninitialized_fill()
Copies the value x into the range [first,last).
- Parameters
-
__first | An input iterator. |
__last | An input iterator. |
__x | The source value. |
- Returns
- Nothing.
Like fill(), but does not require an initialized output range.
Definition at line 201 of file stl_uninitialized.h.
◆ uninitialized_fill_n()
Copies the value x into the range [first,first+n).
- Parameters
-
__first | An input iterator. |
__n | The number of copies to make. |
__x | The source value. |
- Returns
- Nothing.
Like fill_n(), but does not require an initialized output range.

◆ uninitialized_move()
Move-construct from the range [first,last) into result.
- Parameters
-
__first | An input iterator. |
__last | An input iterator. |
__result | An output iterator. |
