const char * source,
sal_Int32 length,
rtl_TextEncoding encoding,
sal_uInt32 flags );

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

Summary
Converts a byte string to a Unicode string, signalling failure.
Parameters
target
    An out parameter receiving the converted string.  Must not be null itself,
    and must contain either null or a pointer to a valid rtl_uString; the
    contents are unspecified if conversion fails (rtl_convertStringToUString
    returns false).

    
source
    The byte string.  May only be null if length is zero.

    
length
    The length of the byte string.  Must be non-negative.

    
encoding
    The text encoding to convert from.  Must be an octet encoding (i.e.,
    rtl_isOctetTextEncoding(encoding) must return true).

    
flags
    A combination of RTL_TEXTTOUNICODE_FLAGS that detail how to do the
    conversion (see rtl_convertTextToUnicode).  RTL_TEXTTOUNICODE_FLAGS_FLUSH
    need not be included, it is implicitly assumed.  Typical uses are either
    RTL_TEXTTOUNICODE_FLAGS_UNDEFINED_ERROR |
    RTL_TEXTTOUNICODE_FLAGS_MBUNDEFINED_ERROR |
    RTL_TEXTTOUNICODE_FLAGS_INVALID_ERROR (fail if a byte or multi-byte sequence
    cannot be converted from the source encoding) or
    OSTRING_TO_OUSTRING_CVTFLAGS (make a best efforts conversion).

    
Return
True if the conversion succeeded, false otherwise.

sal_uInt32 convertFlags );

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

Summary
Create a new Unicode string by converting a byte 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 byte 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
newStr
pointer to the new string.  The pointed-to data must be null or a valid
string.

str
a byte character array.  Need not be null-terminated, but must be at
least as long as the specified len.

len
the length of the byte character array.

encoding
the text encoding to use for conversion.

convertFlags
flags which control the conversion.  Either use
OSTRING_TO_OUSTRING_CVTFLAGS, or see
 for more
details.

extern "C"
void rtl_uString_assign(
rtl_uString * * str,
rtl_uString * 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_uString_getLength
extern "C"
sal_Int32 rtl_uString_getLength(
const rtl_uString * 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_uString_getStr
extern "C"
sal_Unicode * rtl_uString_getStr(
rtl_uString * str );

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

Summary
Return a pointer to the underlying character array of a string.
Parameters
str
    a valid string.

    
Return
a pointer to the null-terminated character array.

rtl_uString_getToken
extern "C"
sal_Int32 rtl_uString_getToken(
rtl_uString * * newStr,
rtl_uString * str,
sal_Int32 token,
sal_Unicode 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_uString * pToken = NULL; sal_Int32 nIndex = 0; do { ... nIndex = rtl_uString_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.

rtl_uString_iterateCodePoints
extern "C"
sal_uInt32 rtl_uString_iterateCodePoints(
const rtl_uString * string,
sal_Int32 * indexUtf16,
sal_Int32 incrementCodePoints );

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

Summary
Iterate through a string based on code points instead of UTF-16 code units.
Description
See Chapter 3 of The Unicode Standard 5.0 (Addison--Wesley, 2006) for definitions of the various terms used in this description. The given string is interpreted as a sequence of zero or more UTF-16 code units. For each index into this sequence (from zero to one less than the length of the sequence, inclusive), a code point represented starting at the given index is computed as follows: - If the UTF-16 code unit addressed by the index constitutes a well-formed UTF-16 code unit sequence, the computed code point is the scalar value encoded by that UTF-16 code unit sequence. - Otherwise, if the index is at least two UTF-16 code units away from the end of the sequence, and the sequence of two UTF-16 code units addressed by the index constitutes a well-formed UTF-16 code unit sequence, the computed code point is the scalar value encoded by that UTF-16 code unit sequence. - Otherwise, the computed code point is the UTF-16 code unit addressed by the index. (This last case catches unmatched surrogates as well as indices pointing into the middle of surrogate pairs.)
Parameters
string
    pointer to a valid string; must not be null.

    
indexUtf16
    pointer to a UTF-16 based index into the given string; must not be null.  On
    entry, the index must be in the range from zero to the length of the string
    (in UTF-16 code units), inclusive.  Upon successful return, the index will
    be updated to address the UTF-16 code unit that is the given
    incrementCodePoints away from the initial index.

    
incrementCodePoints
    the number of code points to move the given *indexUtf16.  If non-negative,
    moving is done after determining the code point at the index.  If negative,
    moving is done before determining the code point at the (then updated)
    index.  The value must be such that the resulting UTF-16 based index is in
    the range from zero to the length of the string (in UTF-16 code units),
    inclusive.

    
Return
the code point (an integer in the range from 0 to 0x10FFFF, inclusive) that is represented within the string starting at the index computed as follows: If incrementCodePoints is non-negative, the index is the initial value of *indexUtf16; if incrementCodePoints is negative, the index is the updated value of *indexUtf16. In either case, the computed index must be in the range from zero to one less than the length of the string (in UTF-16 code units), inclusive.

Parameters
newString
    a non-null pointer to a (possibly null) rtl_uString pointer, which (if
    non-null) will have been passed to rtl_uString_release before the function
    returns.  Upon return, points to the newly allocated string or to null if
    there was either an out-of-memory condition or the resulting number of
    UTF-16 code units would have been larger than SAL_MAX_INT32.  The newly
    allocated string (if any) must ultimately be passed to rtl_uString_release.

    
codePoints
    an array of at least codePointCount code points, which each must be in the
    range from 0 to 0x10FFFF, inclusive.  May be null if codePointCount is zero.

    
codePointCount
    the non-negative number of code points.

Summary
Compare two strings with a maximum count of characters, ignoring the case of ASCII characters.
Description
The comparison is based on the numeric value of each character in the strings and returns a value indicating their relationship. Character values between 65 and 90 (ASCII A--Z) are interpreted as values between 97 and 122 (ASCII a--z). This function cannot be used for language-specific sorting. Since this function is optimized for performance, the ASCII character values are not converted in any way. The caller has to make sure that all ASCII characters are in the allowed range of 0 and 127, inclusive.
Parameters
first
the first string to be compared.  Need not be null-terminated, but must be
at least as long as the specified firstLen.

firstLen
the length of the first string.

second
the second null-terminated ASCII string which is compared with the first
one.

shortenedLen
the maximum number of characters to compare.  This length can be greater
or smaller than the lengths of the two strings.

Return
0 if both substrings are equal, a value less than 0 if the first substring is less than the second substring, and a value greater than 0 if the first substring is greater than the second substring.
