std::string platform::file_name_from_path

(

std::string_view

path

)

Return the last path component from a file path.

Parameters

character

Character to inspect.

Returns

True when the character is a supported path separator.

join_path()

std::string platform::join_path	(	const std::string &	left,
		const std::string &	right )

path_has_prefix()

bool platform::path_has_prefix	(	const std::string &	path,
		const std::string &	prefix )

Return whether a path begins with the requested prefix.

Parameters

path	Full path to inspect.
prefix	Prefix to compare against.

Returns

True when the path starts with the prefix.

preferred_path_separator()

char platform::preferred_path_separator

(

)

Return the preferred path separator for the active platform.

Returns

Preferred path separator character.

try_get_file_size()

bool platform::try_get_file_size	(	std::string_view	path,
		std::uint64_t *	sizeBytes = nullptr )

Try to read the size of a regular file.

Parameters

path	File path to inspect.
sizeBytes	Optional output for the file size in bytes.

Returns

True when the path exists and is a regular file.
