Description

function BreakToWidth( const aWideString: WideString; const aWidth: integer ): WideString;

break a string at a preferred position into lines

function CodeBlockFromChar(const C: WideChar): Cardinal;

function CodePageFromLocale(Language: LCID): Integer;

function StrAllocW(Size: Cardinal): PWideChar;

Allocates a buffer for a null-terminated wide string and returns a pointer to the first character of the string.

function StrBufSizeW(Str: PWideChar): Cardinal;

Returns max number of wide characters that can be stored in a buffer allocated by StrAllocW.

function StrCatW(Dest, Source: PWideChar): PWideChar;

appends a copy of Source to the end of Dest and returns the concatenated string

function StrCompW(Str1, Str2: PWideChar): Integer;

compares Str1 to Str2 (binary comparation)

function StrCopyW(Dest, Source: PWideChar): PWideChar;

copies Source to Dest and returns Dest

procedure StrDisposeW(Str: PWideChar);

releases a string allocated with StrNew.

function StrECopyW(Dest, Source: PWideChar): PWideChar;

copies Source to Dest and returns a pointer to the null character ending the string

function StrEndW(Str: PWideChar): PWideChar;

returns a pointer to the end of a null terminated string

function StrICompW(Str1, Str2: PWideChar): Integer;

compares Str1 to Str2 without case sensitivity (binary comparation)

function StrLCatW(Dest, Source: PWideChar; MaxLen: Cardinal): PWideChar;

appends a specified maximum number of WideCharacters to string

function StrLCompW(Str1, Str2: PWideChar; MaxLen: Cardinal): Integer;

compares a specified maximum number of charaters in two strings

function StrLCopyW(Dest, Source: PWideChar; MaxLen: Cardinal): PWideChar;

copies a specified maximum number of characters from Source to Dest

function StrLenW(Str: PWideChar): Cardinal;

returns number of characters in a string excluding the null terminator

function StrLICompW(Str1, Str2: PWideChar; MaxLen: Cardinal): Integer;

compares strings up to a specified maximum number of characters, not case sensitive

function StrLowerW(Str: PWideChar): PWideChar;

converts Str to lower case and returns it

function StrMoveW(Dest, Source: PWideChar; Count: Cardinal): PWideChar;

Copies the specified number of characters to the destination string and returns Dest also as result. Dest must have enough room to store at least Count characters.

function StrNewW(Str: PWideChar): PWideChar;

Duplicates the given string (if not nil) and returns the address of the new string.

function StrNScanW(S1, S2: PWideChar): Integer;

determines where (in S1) the first time one of the characters of S2 appear. The result is the length of a string part of S1 where none of the characters of S2 do appear (not counting the trailing #0 and starting with position 0 in S1).

function StrPCopyW(Dest: PWideChar; const Source: String): PWideChar;

copies a Pascal-style string to a null-terminated wide string

function StrPLCopyW(Dest: PWideChar; const Source: String; MaxLen: Cardinal): PWideChar;

copies characters from a Pascal-style string into a null-terminated wide string

function StrPosW(Str, SubStr: PWideChar): PWideChar;

returns a pointer to the first occurance of SubStr in Str

function StrRNScanW(S1, S2: PWideChar): Integer;

This function does the same as StrRNScanW but uses S1 in reverse order. This means S1 points to the last character of a string, is traveresed reversely and terminates with a starting #0. This is useful for parsing strings stored in reversed macro buffers etc.

function StrRScanW(Str: PWideChar; Chr: WideChar): PWideChar;

returns a pointer to the last occurance of Chr in Str

function StrScanW(Str: PWideChar; Chr: WideChar; StrLen: Cardinal): PWideChar; overload;

returns a pointer to first occurrence of a specified character in a string or nil if not found

function StrScanW(Str: PWideChar; Chr: WideChar): PWideChar; overload;

returns a pointer to first occurrence of a specified character in a string

procedure StrSwapByteOrder(Str: PWideChar);

exchanges in each character of the given string the low order and high order byte to go from LSB to MSB and vice versa. EAX contains address of string

function StrTitleW(Str: PWideChar): PWideChar;

converts Str to title case and returns it

function StrUpperW(Str: PWideChar): PWideChar;

converts Str to upper case and returns it
