Function Documentation

SEXP Rf_mkCharLenCE	(	const char *	text,
		int	length,
		cetype_t	encoding
	)

Create a CXXR::String object for specified text and encoding.

If no CXXR::String with the specified text and encoding currently exists, one will be created. Otherwise a pointer to the existing CXXR::String will be returned.

Parameters:

text	The text of the string to be created, possibly including embedded null characters. The encoding is assumed to be CE_NATIVE.
length	The length of the string pointed to by text. Must be nonnegative. The created string will comprise the text plus an appended null byte.
encoding	The encoding of the required String. Only CE_NATIVE, CE_UTF8 or CE_LATIN1 are permitted in this context (checked).

Returns:

Pointer to the created string.
