Function Documentation

◆ MacOSStringCompare()

int MacOSStringCompare	(	std::string_view	s1,
		std::string_view	s2
	)

Compares two strings using case insensitive natural sort.

Parameters

s1	First string to compare.
s2	Second string to compare.

Returns: 1 if s1 < s2, 2 if s1 == s2, 3 if s1 > s2, or 0 if not supported by the OS.

Definition at line 329 of file string_osx.cpp.

◆ MacOSStringContains()

int MacOSStringContains	(	const std::string_view	str,
		const std::string_view	value,
		bool	case_insensitive
	)

Search if a string is contained in another string using the current locale.

Parameters

str	String to search in.
value	String to search for.
case_insensitive	Search case-insensitive.

Returns: 1 if value was found, 0 if it was not found, or -1 if not supported by the OS.
