Definition: macros.h:47

Supply an ASCII string literal together with its length and text encoding.

This macro can be used to compute (some of) the arguments in function calls like rtl::OUString(RTL_CONSTASCII_USTRINGPARAM("foo")).

Parameters

  constAsciiStr | must be an expression of type "(possibly cv-qualified reference to) array of (possibly cv-qualified) char." Each element of the referenced array must represent an ASCII value in the range 0x00–0x7F. The last element of the referenced array is not considered part of the represented ASCII string, and its value should be 0x00. Depending on where this macro is used, the nature of the supplied expression might be further restricted.

## ◆ rtl_convertStringToUString()

SAL_DLLPUBLIC sal_Bool rtl_convertStringToUString | ( | rtl_uString ** | target,
|  | char const * | source,
|  | sal_Int32 | length,
|  | rtl_TextEncoding | encoding,
|  | sal_uInt32 | flags
| ) |  |

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).

Returns
  True if the conversion succeeded, false otherwise.

Since
  UDK 3.2.9

## ◆ rtl_string2UString()

SAL_DLLPUBLIC void rtl_string2UString | ( | rtl_uString ** | newStr,
|  | const sal_Char * | str,
|  | sal_Int32 | len,
|  | rtl_TextEncoding | encoding,
|  | sal_uInt32 | convertFlags
| ) |  |

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

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.

|  | sal_Int32 | token,
|  | sal_Unicode | cTok,
|  | sal_Int32 | idx
| ) |  |

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

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 separates the tokens.
  idx | the position at which searching for the token starts. Must not be greater than the length of str.

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

Return a canonical representation for a string.

A pool of strings, initially empty is maintained privately by the string class. On invocation, if present in the pool the original string will be returned. Otherwise this string, or a copy thereof will be added to the pool and returned.

Parameters

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

If an out-of-memory condition occurs, newStr will point to a null pointer upon return.

Parameters

  str | pointer to the string to be interned.

## ◆ rtl_uString_iterateCodePoints()

SAL_DLLPUBLIC sal_uInt32 rtl_uString_iterateCodePoints | ( | rtl_uString const * | string,
|  | sal_Int32 * | indexUtf16,
|  | sal_Int32 | incrementCodePoints
| ) |  |

Iterate through a string based on code points instead of UTF-16 code units.

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.

Returns
  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.

|  | sal_Int32 | idx,
|  | sal_Int32 | count,
|  | rtl_uString * | subStr
| ) |  |

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

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

  newStr | pointer to the new string. The pointed-to data must be null or a valid string.
  str | a valid string.
  idx | the index into str at which to start replacement. Must be between 0 and the length of str, inclusive.
  count | the number of characters 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.

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

The new string results from replacing all characters with values between 65 and 90 (ASCII A–Z) by values between 97 and 122 (ASCII a–z).

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.
