AuthAzureSAS Unicode C Reference Documentation

AuthAzureSAS

Current Version: 9.5.0.73

Provides general functionality for Azure Shared Access Signature (SAS) Authorization.

This class is introduced in Chilkat v9.5.0.65.

Create/Dispose

HCkAuthAzureSASW instance = CkAuthAzureSASW_Create();
// ...
CkAuthAzureSASW_Dispose(instance);
HCkAuthAzureSASW CkAuthAzureSASW_Create(void);

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

void CkAuthAzureSASW_Dispose(HCkAuthAzureSASW handle);

Objects created by calling CkAuthAzureSASW_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 CkAuthAzureSASW_Dispose.

Properties

AccessKey
void CkAuthAzureSASW_getAccessKey(HCkAuthAzureSASW cHandle, HCkString retval);
void CkAuthAzureSASW_putAccessKey(HCkAuthAzureSASW cHandle, const wchar_t *newVal);
const wchar_t *CkAuthAzureSASW_accessKey(HCkAuthAzureSASW cHandle);
Introduced in version 9.5.0.65

This is the signing key (access key) that must be kept private. It is a base64 string such as "abdTvCZFFoWUyre6erlNN+IOb9qhXgDsyhrxmZvpmxqFDwpl9oD0X9Fy0hIQa6L5UohznRLmkCtUYySO4Y2eaw=="

DebugLogFilePath
void CkAuthAzureSASW_getDebugLogFilePath(HCkAuthAzureSASW cHandle, HCkString retval);
void CkAuthAzureSASW_putDebugLogFilePath(HCkAuthAzureSASW cHandle, const wchar_t *newVal);
const wchar_t *CkAuthAzureSASW_debugLogFilePath(HCkAuthAzureSASW cHandle);

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

  1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
  2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
  3. there is an internal problem (bug) in the Chilkat code that causes the hang.

top
LastErrorHtml
void CkAuthAzureSASW_getLastErrorHtml(HCkAuthAzureSASW cHandle, HCkString retval);
const wchar_t *CkAuthAzureSASW_lastErrorHtml(HCkAuthAzureSASW cHandle);

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorText
void CkAuthAzureSASW_getLastErrorText(HCkAuthAzureSASW cHandle, HCkString retval);
const wchar_t *CkAuthAzureSASW_lastErrorText(HCkAuthAzureSASW cHandle);

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorXml
void CkAuthAzureSASW_getLastErrorXml(HCkAuthAzureSASW cHandle, HCkString retval);
const wchar_t *CkAuthAzureSASW_lastErrorXml(HCkAuthAzureSASW cHandle);

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastMethodSuccess
BOOL CkAuthAzureSASW_getLastMethodSuccess(HCkAuthAzureSASW cHandle);
void CkAuthAzureSASW_putLastMethodSuccess(HCkAuthAzureSASW cHandle, BOOL newVal);
Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of TRUE indicates success, a value of FALSE indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

  • Any method that returns a string.
  • Any method returning a Chilkat object, binary bytes, or a date/time.
  • Any method returning a standard boolean status value where success = TRUE and failure = FALSE.
  • Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to TRUE. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
StringToSign
void CkAuthAzureSASW_getStringToSign(HCkAuthAzureSASW cHandle, HCkString retval);
void CkAuthAzureSASW_putStringToSign(HCkAuthAzureSASW cHandle, const wchar_t *newVal);
const wchar_t *CkAuthAzureSASW_stringToSign(HCkAuthAzureSASW cHandle);
Introduced in version 9.5.0.65

Defines the format of the string to sign.

The format is specified as a comma-separated list of names. For example:

signedpermissions,signedstart,signedexpiry,canonicalizedresource,signedidentifier,signedIP,signedProtocol,signedversion,rscc,rscd,rsce,rscl,rsct
This will result in an actual string-to-sign that is composed of the values for each name separated by newline (LF) chars. For example:
signedpermissions + "\n" +  
signedstart + "\n" +  
signedexpiry + "\n" +  
canonicalizedresource + "\n" +  
signedidentifier + "\n" +  
signedIP + "\n" +  
signedProtocol + "\n" +  
signedversion + "\n" +  
rscc + "\n" +  
rscd + "\n" +  
rsce + "\n" +  
rscl + "\n" +  
rsct

top
VerboseLogging
BOOL CkAuthAzureSASW_getVerboseLogging(HCkAuthAzureSASW cHandle);
void CkAuthAzureSASW_putVerboseLogging(HCkAuthAzureSASW cHandle, BOOL newVal);

If set to TRUE, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is FALSE. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
void CkAuthAzureSASW_getVersion(HCkAuthAzureSASW cHandle, HCkString retval);
const wchar_t *CkAuthAzureSASW_version(HCkAuthAzureSASW cHandle);

Version of the component/library, such as "9.5.0.63"
