struct	_swappable_with_helper< T, U, void_t< decltype(swap(declval< T >(), declval< U >()))> >
struct	add_const
	Provides the member typedef type which is the same as T, except it has a cv-qualifier added (unless T is a function, a reference, or already has this cv-qualifier). Adds const. More...
struct	add_cv
	Provides the member typedef type which is the same as T, except it has a cv-qualifier added (unless T is a function, a reference, or already has this cv-qualifier). Adds both const and volatile. More...
struct	add_lvalue_reference
	Creates a lvalue reference type of T. More...
struct	add_pointer
	If T is a reference type, then provides the member typedef type which is a pointer to the referred type. Otherwise, if T names an object type, a function type that is not cv- or ref-qualified, or a (possibly cv-qualified) void type, provides the member typedef type which is the type T*. Otherwise (if T is a cv- or ref-qualified function type), provides the member typedef type which is the type T. The behavior of a program that adds specializations for add_pointer is undefined. More...

struct	aligned_storage
	Provides the nested type type, which is a trivial standard-layout type suitable for use as uninitialized storage for any object whose size is at most Len and whose alignment requirement is a divisor of Align. The default value of Align is the most stringent (the largest) alignment requirement for any object whose size is at most Len.

If sizeof...(Types) == 0 or if any of the types in Types is not a complete object type, the behavior is undefined. It is implementation-defined whether any extended alignment is supported. The behavior of a program that adds specializations for aligned_union is undefined. More...

Instances of reference_wrapper are objects (they can be copied or stored in containers) but they are implicitly convertible to T&, so that they can be used as arguments with the functions that take the underlying type by reference. If the stored reference is Callable, reference_wrapper is callable with the same arguments. More...

align()

auto align ( etl::size_t alignment, etl::size_t size, void *& ptr, etl::size_t & space ) -> void*

inlinenodiscardnoexcept

Given a pointer ptr to a buffer of size space, returns a pointer aligned by the specified alignment for size number of bytes and decreases space argument by the number of bytes used for alignment. The first aligned address is returned.

The function modifies the pointer only if it would be possible to fit the wanted number of bytes aligned by the given alignment into the buffer. If the buffer is too small, the function does nothing and returns nullptr.

move()

template<typename T>

auto move ( T && t ) -> etl::remove_reference_t<T>&&

constexprnoexcept

move is used to indicate that an object t may be "moved from", i.e. allowing the efficient transfer of resources from t to another object. In particular, move produces an xvalue expression that identifies its argument t. It is exactly equivalent to a static_cast to an rvalue reference type.

Returns

static_cast<remove_reference_t<T>&&>(t)

Same as etl::move unless the type's move constructor could throw and the type is copyable, in which case an lvalue-reference is returned instead.

constexpr

Appends at most count wide characters from the wide string pointed to by src to the end of the character string pointed to by dest, stopping if the null terminator is copied. The wide character src[0] replaces the null terminator at the end of dest. The null terminator is always appended in the end (so the maximum number of wide characters the function may write is count+1).

The destination byte string must have enough space for the contents of both dest and src plus the terminating null character, except that the size of src is limited to count. The behavior is undefined if the strings overlap.

wcsncmp()

auto wcsncmp ( wchar_t const * lhs, wchar_t const * rhs, etl::size_t count ) -> int

nodiscardconstexpr

Compares at most count wide characters of two null-terminated wide strings. The comparison is done lexicographically.

The sign of the result is the sign of the difference between the values of the first pair of wide characters that differ in the strings being compared.

The behavior is undefined if lhs or rhs are not pointers to null-terminated strings.

wcsncpy()

auto wcsncpy ( wchar_t * dest, wchar_t const * src, etl::size_t const count ) -> wchar_t*

constexpr

Copies at most count characters of the wide string pointed to by src (including the terminating null wide character) to wide character array pointed to by dest.

If count is reached before the entire string src was copied, the resulting character array is not null-terminated. If, after copying the terminating null character from src, count is not reached, additional null characters are written to dest until the total of count characters have been written. If the strings overlap, the behavior is undefined.

Returns

auto wcsspn ( wchar_t const * dest, wchar_t const * src ) -> etl::size_t

nodiscardconstexprnoexcept

Returns the length of the maximum initial segment of the wide string pointed to by dest, that consists of only the characters found in wide string pointed to by src.

https://en.cppreference.com/w/cpp/string/wide/wcsspn

wcsstr() [1/2]

auto wcsstr ( wchar_t * haystack, wchar_t * needle ) -> wchar_t*

nodiscardconstexprnoexcept

Finds the first occurrence of the wide string needle in the wide string pointed to by haystack. The terminating null characters are not compared.

https://en.cppreference.com/w/cpp/string/wide/wcspbrk

wcsstr() [2/2]

auto wcsstr ( wchar_t const * haystack, wchar_t const * needle ) -> wchar_t const*

nodiscardconstexprnoexcept

Finds the first occurrence of the wide string needle in the wide string pointed to by haystack. The terminating null characters are not compared.

https://en.cppreference.com/w/cpp/string/wide/wcspbrk

wmemchr() [1/2]

auto wmemchr ( wchar_t * ptr, wchar_t ch, etl::size_t count ) -> wchar_t*

nodiscardconstexprnoexcept

Locates the first occurrence of wide character ch in the initial count wide characters of the wide character array pointed to by ptr.

If count is zero, the function returns a null pointer.

https://en.cppreference.com/w/cpp/string/wide/wmemchr

wmemchr() [2/2]

auto wmemchr ( wchar_t const * ptr, wchar_t ch, etl::size_t count ) -> wchar_t const*

nodiscardconstexprnoexcept

Locates the first occurrence of wide character ch in the initial count wide characters of the wide character array pointed to by ptr.

If count is zero, the function returns a null pointer.

https://en.cppreference.com/w/cpp/string/wide/wmemchr

wmemcmp()

auto wmemcmp ( wchar_t const * lhs, wchar_t const * rhs, etl::size_t count ) -> int

constexprnoexcept

Compares the first count wide characters of the wide character arrays pointed to by lhs and rhs. The comparison is done lexicographically.

The sign of the result is the sign of the difference between the values of the first pair of wide characters that differ in the arrays being compared. If count is zero, the function does nothing.

https://en.cppreference.com/w/cpp/string/wide/wmemcmp

wmemcpy()

auto wmemcpy ( wchar_t * dest, wchar_t const * src, etl::size_t count ) -> wchar_t*

constexprnoexcept

Copies exactly count successive wide characters from the wide character array pointed to by src to the wide character array pointed to by dest. If the objects overlap, the behavior is undefined. If count is zero, the function does nothing.

https://en.cppreference.com/w/cpp/string/wide/wmemcpy

wmemmove()

auto wmemmove ( wchar_t * dest, wchar_t const * src, etl::size_t count ) -> wchar_t*

constexprnoexcept

Copies exactly count successive wide characters from the wide character array pointed to by src to the wide character array pointed to by dest.

If count is zero, the function does nothing. The arrays may overlap: copying takes place as if the wide characters were copied to a temporary wide character array and then copied from the temporary array to dest. This function is not locale-sensitive and pays no attention to the values of the wchar_t objects it copies: nulls as well as invalid characters are copied too.

https://en.cppreference.com/w/cpp/string/wide/wmemmove

wmemset()

auto wmemset ( wchar_t * dest, wchar_t ch, etl::size_t count ) -> wchar_t*

constexprnoexcept

Copies the wide character ch into each of the first count wide characters of the wide character array pointed to by dest.

If overflow occurs, the behavior is undefined. If count is zero, the function does nothing.

byte

enum TETL_MAY_ALIAS byte

strong

etl::byte is a distinct type that implements the concept of byte as specified in the C++ language definition.

Like char and unsigned char, it can be used to access raw memory occupied by other objects, but unlike those types, it is not a character type and is not an arithmetic type. A byte is only a collection of bits, and the only operators defined for it are the bitwise ones.
