Function Documentation

memcmp()

int memcmp	(	const std::string_view &	lhs,
		const std::string_view &	rhs )

Compare views with ordering.

Parameters

lhs	input view
rhs	input view

Returns

The ordered comparison value.

• -1 if lhs is less than rhs
• 1 if lhs is greater than rhs
• 0 if the views have identical content.

If one view is the prefix of the other, the shorter view is less (first in the ordering).

Note

For string views, there is no difference between strcmp and memcmp.

memcpy()

void * memcpy ( void * dst, const std::string_view & src )

inline

Copy bytes.

Parameters

dst	Destination buffer.
src	Original string.

Returns

dest

This is a convenience for

memcpy(dst, src.data(), size.size());

Therefore dst must point at a buffer large enough to hold src. If this is not already determined, then presuming DST_SIZE is the size of the buffer at dst

memcpy(dst, src.prefix(DST_SIZE));

strcasecmp()

int strcasecmp	(	const std::string_view &	lhs,
		const std::string_view &	rhs )

Compare views with ordering, ignoring case.

Parameters

lhs	input view
rhs	input view

Returns

The ordered comparison value.

• -1 if lhs is less than rhs
• 1 if lhs is greater than rhs
• 0 if the views have identical content.

If one view is the prefix of the other, the shorter view is less (first in the ordering).

strcmp()

int strcmp ( const std::string_view & lhs, const std::string_view & rhs )

inline

Compare views with ordering.

Parameters

lhs	input view
rhs	input view

Returns

The ordered comparison value.

• -1 if lhs is less than rhs
• 1 if lhs is greater than rhs
• 0 if the views have identical content.

If one view is the prefix of the other, the shorter view is less (first in the ordering).
