Function Documentation

__from_chars_alnum()

template<bool _DecOnly, typename _Tp >

bool std::__detail::__from_chars_alnum	(	const char *&	__first,
		const char *	__last,
		_Tp &	__val,
		int	__base
	)

std::from_chars implementation for integers in any base. If _DecOnly is true, then we may assume __base is at most 10.

Definition at line 510 of file charconv.

__from_chars_pow2_base()

template<bool _DecOnly, typename _Tp >

bool std::__detail::__from_chars_pow2_base	(	const char *&	__first,
		const char *	__last,
		_Tp &	__val,
		int	__base
	)

std::from_chars implementation for integers in a power-of-two base. If _DecOnly is true, then we may assume __base is at most 8.

Definition at line 453 of file charconv.

operator<<() [1/2]

template<typename _CharT , typename _Traits , typename _String >

std::basic_ostream<_CharT, _Traits>& std::__detail::operator<<	(	std::basic_ostream< _CharT, _Traits > &	__os,
		const _Quoted_string< _String, _CharT > &	__str
	)

Inserter for quoted strings.

_GLIBCXX_RESOLVE_LIB_DEFECTS DR 2344 quoted()'s interaction with padding is unclear

Definition at line 1 of file quoted_string.h.

operator<<() [2/2]

template<typename _CharT , typename _Traits >

std::basic_ostream<_CharT, _Traits>& std::__detail::operator<<	(	std::basic_ostream< _CharT, _Traits > &	__os,
		const _Quoted_string< const _CharT *, _CharT > &	__str
	)

Inserter for quoted strings.

_GLIBCXX_RESOLVE_LIB_DEFECTS DR 2344 quoted()'s interaction with padding is unclear

Definition at line 1 of file quoted_string.h.

operator>>()

template<typename _CharT , typename _Traits , typename _Alloc >

std::basic_istream<_CharT, _Traits>& std::__detail::operator>>	(	std::basic_istream< _CharT, _Traits > &	__is,
		const _Quoted_string< basic_string< _CharT, _Traits, _Alloc > &, _CharT > &	__str
	)

Extractor for delimited strings. The left and right delimiters can be different.

Definition at line 139 of file quoted_string.h.
