CkString C Reference Documentation

CkString

Current Version: 9.5.0.97

The Chilkat string class.

Create/Dispose

HCkString instance = CkString_Create();
// ...
CkString_Dispose(instance);
HCkString CkString_Create(void);

Creates an instance of the HCkString object and returns a handle ("void *" pointer). The handle is passed in the 1st argument for the functions listed on this page.

void CkString_Dispose(HCkString handle);

Objects created by calling CkString_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function. Also, any handle returned by a Chilkat "C" function must also be freed by the application by calling the appropriate Dispose method, such as CkString_Dispose.

The str is appended to end of this instance.

top
appendAnsi
void CkString_appendAnsi(HCkString cHandle, const char *str);

Appends an ANSI string to the end of this instance. str should always be a null terminated ANSI string regardless of the Utf8 property setting.

top
appendChar
void CkString_appendChar(HCkString cHandle, char c);

Appends a single ANSI character to the end of this instance.

top
appendCurrentDateRfc822
void CkString_appendCurrentDateRfc822(HCkString cHandle);

Appends the current date/time to the end of this instance. The date/time is formatted according to the RFC822 standard, which is the typical format used in the "Date" header field of email. For example: "Fri, 27 Jul 2012 17:41:41 -0500"

top

Appends a string of any character encoding to the end of this instance. Examples of charsetEncoding are: Shift_JIS, windows-1255, iso-8859-2, gb2312, etc. The str should point to a null-terminated string that uses the charset specified by charsetEncoding.

More Information and Examples
top
appendHexData
void CkString_appendHexData(HCkString cHandle, const unsigned char *byteData, unsigned long numBytes);

Converts the binary data to a hexidecimal string representation and appends to the end of this instance. The hex data is appended in 2-byte chunks with 16 bytes per line. For example:

6861 6C6C 6861 6C6C 6861 6C6C 6861 6C6C
6861 6C6C 6861 6C6C 6861 6C6C 6861 6C6C

top
appendInt

Appends the decimal string representation of an integer to the end of this instance.

top
appendLastWindowsError
void CkString_appendLastWindowsError(HCkString cHandle);

For many Win32 Platform SDK functions, such as CreateFile, error information must be retrieved by using the Win32 functions GetLastError and FormatMessage. This method calls these Win32 functions to format the error and appends it to the string.

This method would only be used by Win32 applications that call Platform SDK functions.

top
appendN
void CkString_appendN(HCkString cHandle, const char *str, unsigned long numBytes);

Appends N bytes of character data to the end of this instance. If the Utf8 property is set to TRUE, then str should point to characters in the utf-8 encoding, otherwise it should point to characters using the ANSI encoding. Note: numBytes is not necessarily the number of characters. It is the length, in bytes, of the string to be appended. This method exists to allow for non-null terminated strings to be appended.

top
appendNU
void CkString_appendNU(HCkString cHandle, const wchar_t * wideStr, int numChars);

top
appendRandom
void CkString_appendRandom(HCkString cHandle, int numBytes, const char *encoding);

Appends numBytes random bytes to the end of this instance. Because arbitrary byte values in the range 0 to 255 do not necessarily represent valid characters, the bytes must be encoded to a string friendly representation such as hex, base64, etc. The encoding specifies the encoding to be used. Possible values are "hex", "base64", "quoted-printable", "asc", or "url".

The "replaceAllOccurances" method is called, replacing longer substrings with shorter replacements. The actual string length will become shorter than the internal buffer space that is allocated. The minimizeMemory method will, if necessary, allocate a new internal buffer that is exactly the size needed to hold the current contents of the string, copy the string to the new internal buffer, and deallocate the old buffer.

The Chilkat string obfuscation algorithm works by taking the utf-8 bytes of the string, base64 encoding it, and then scrambling the letters of the base64 encoded string. It is deterministic in that the same string will always obfuscate to the same result. It is not a secure way of encrypting a string. It is only meant to be a simple means of transforming a string into something unintelligible.

Unobfuscates the string.

The Chilkat string obfuscation algorithm works by taking the utf-8 bytes of the string, base64 encoding it, and then scrambling the letters of the base64 encoded string. It is deterministic in that the same string will always obfuscate to the same result. It is not a secure way of encrypting a string. It is only meant to be a simple means of transforming a string into something unintelligible.

urlDecodeW
void CkString_urlDecodeW(HCkString cHandle, const wchar_t * charsetEncoding);

The utf-16 version of the urlDecode method.

urlEncode
void CkString_urlEncode(HCkString cHandle, const char *charsetEncoding);

URL encodes the string. The string is first converted to the specified charset encoding, and those bytes are URL-encoded. The contents of the string are replaced with the URL-encoded result.
