Local< String > v8::String::New	(	const char *	data,
		int	length = `-1`
	)			`[static]`

Allocates a new string from either utf-8 encoded or ascii data. The second parameter 'length' gives the buffer length. If the data is utf-8 encoded, the caller must be careful to supply the length parameter. If it is not given, the function calls 'strlen' to determine the buffer length, it might be wrong if 'data' contains a null character.

Local< String > v8::String::NewExternal ( ExternalAsciiStringResource * resource ) [static]

Creates a new external string using the ascii data defined in the given resource. The resource is deleted when the external string is no longer live on V8's heap. The caller of this function should not delete or modify the resource. Neither should the underlying buffer be deallocated or modified except through the destructor of the external string resource.

int v8::String::Write	(	uint16_t *	buffer,
		int	start = `0`,
		int	length = `-1`
	)

Write the contents of the string to an external buffer. If no arguments are given, expects the buffer to be large enough to hold the entire string and NULL terminator. Copies the contents of the string and the NULL terminator into the buffer.

Copies up to length characters into the output buffer. Only null-terminates if there is enough space in the buffer.

引数:

	buffer	The buffer into which the string will be copied.
	start	The starting position within the string at which copying begins.
	length	The number of bytes to copy from the string.

戻り値:: The number of characters copied to the buffer excluding the NULL terminator.
