rtl_convertUStringToString

extern "C"

rtl_String * *	pTarget,
const sal_Unicode *	pSource,
sal_Int32	nLength,
rtl_TextEncoding	nEncoding,
sal_uInt32	nFlags );

virtual	abstract	const	volatile	template	static	inline	C-linkage
NO	NO	NO	NO	NO	NO	NO	YES

Summary

Converts a Unicode string to a byte string, signalling failure.

Parameters

pTarget	An out parameter receiving the converted string. Must not be null itself, and must contain either null or a pointer to a valid rtl_String; the contents are not modified if conversion fails (rtl_convertUStringToString returns false).
pSource	The Unicode string. May only be null if nLength is zero.
nLength	The length of the Unicode string. Must be non-negative.
nEncoding	The text encoding to convert into. Must be an octet encoding (i.e., rtl_isOctetTextEncoding(nEncoding) must return true).
nFlags	A combination of RTL_UNICODETOTEXT_FLAGS that detail how to do the conversion (see rtl_convertUnicodeToText). RTL_UNICODETOTEXT_FLAGS_FLUSH need not be included, it is implicitly assumed. Typical uses are either RTL_UNICODETOTEXT_FLAGS_UNDEFINED_ERROR \| RTL_UNICODETOTEXT_FLAGS_INVALID_ERROR (fail if a Unicode character cannot be converted to the target nEncoding) or OUSTRING_TO_OSTRING_CVTFLAGS (make a best efforts conversion).

Return

True if the conversion succeeded, false otherwise.

radix

    the radix.  Must be between RTL_STR_MIN_RADIX (2) and RTL_STR_MAX_RADIX
    (36), inclusive.

rtl_String * *	str,
rtl_String *	rightValue );

virtual	abstract	const	volatile	template	static	inline	C-linkage
NO	NO	NO	NO	NO	NO	NO	YES

Summary

Assign a new value to a string.

Description

First releases any value str might currently hold, then acquires rightValue.

Parameters

str	pointer to the string. The pointed-to data must be null or a valid string.
rightValue	a valid string.

rtl_string_getLength

extern "C"
sal_Int32 rtl_string_getLength(

const rtl_String *

str );

virtual	abstract	const	volatile	template	static	inline	C-linkage
NO	NO	NO	NO	NO	NO	NO	YES

Summary

Return the length of a string.

Description

The length is equal to the number of characters in the string.

Parameters

str	a valid string.

Return

the length of the string.

rtl_string_getStr

extern "C"
sal_Char * rtl_string_getStr(

rtl_String *

str );

virtual	abstract	const	volatile	template	static	inline	C-linkage
NO	NO	NO	NO	NO	NO	NO	YES

Summary

rtl_string_getToken

extern "C"
sal_Int32 rtl_string_getToken(

rtl_String * *	newStr,
rtl_String *	str,
sal_Int32	token,
sal_Char	cTok,
sal_Int32	idx );

virtual	abstract	const	volatile	template	static	inline	C-linkage
NO	NO	NO	NO	NO	NO	NO	YES

Summary

Create a new string by extracting a single token from another string.

Description

Starting at index, the token's next token is searched for. If there is no such token, the result is an empty string. Otherwise, all characters from the start of that token and up to, but not including the next occurrence of cTok make up the resulting token. The return value is the position of the next token, or -1 if no more tokens follow. Example code could look like rtl_String * pToken = NULL; sal_Int32 nIndex = 0; do { ... nIndex = rtl_string_getToken(&pToken, pStr, 0, ';', nIndex); ... } while (nIndex >= 0); The new string does not necessarily have a reference count of 1, so it must not be modified without checking the reference count. This function does not handle out-of-memory conditions.

Parameters

newStr	pointer to the new string. The pointed-to data must be null or a valid string. If either token or index is negative, an empty token is stored in newStr (and -1 is returned).
str	a valid string.
token	the number of the token to return, starting at index.
cTok	the character that seperates the tokens.
index	the position at which searching for the token starts. Must not be greater than the length of str.

Return

the index of the next token, or -1 if no more tokens follow.

Summary

Create a new string by replacing a substring of another string.

Description

The new string results from replacing a number of characters (count), starting at the specified position (index) in the original string (str), with some new substring (subStr). If subStr is null, than only a number of characters is deleted. The new string does not necessarily have a reference count of 1, so it must not be modified without checking the reference count. This function does not handle out-of-memory conditions.

Parameters

str	a valid string.
index	the index into str at which to start replacement. Must be between 0 and the length of str, inclusive.
count	the number of charcters to remove. Must not be negative, and the sum of index and count must not exceed the length of str.
subStr	either null or a valid string to be inserted.

NO	NO	NO	NO	NO	NO	NO	YES

Summary

Create a new string by converting all ASCII uppercase letters to lowercase within another string.

Description

This function cannot be used for language-specific conversion. The new string does not necessarily have a reference count of 1 (in cases where no characters need to be converted), so it must not be modified without checking the reference count. This function does not handle out-of-memory conditions.

Parameters

newStr	pointer to the new string. The pointed-to data must be null or a valid string.
str	a valid string.

Summary

Create a new byte string by converting a Unicode string, using a specific text encoding.

Description

The lengths of the byte string and the Unicode string may differ (e.g., for double-byte encodings, UTF-7, UTF-8). If the length of the Unicode string is greater than zero, the reference count of the new string will be 1. If an out-of-memory condition occurs, newStr will point to a null pointer upon return.

Parameters

str	a Unicode character array. Need not be null-terminated, but must be at least as long as the specified len.
len	the length of the Unicode character array.
encoding	the text encoding to use for conversion.
