C Client error handling

For C Client applications, functions return an error code of type E_BNS_ERROR_CODE, which is defined in the header file bnsErrorCodes.h.

When no errors are detected, the return value is _BNS_OK (0).

To get extended error information, use the following function:

bns__ErrorInfo* bns__get_last_error(bns__Connection client)

The struct bns__ErrorInfo, which is defined in the bnsDataStructs.h header file, contains the error code and a textual description of the error:

struct bns__ErrorInfo

{

    E_BNS_ERROR_CODE error_code;

    wchar_t *description;

};

Possible errors can be grouped together as follows:

• Communication errors with the system. These errors are typically returned from the network or web server.
• System-specific errors that are returned from the system.
