ucErrorMessage

See Also: ucError, Error Handling, ucRaiseError

Returns an error message.

ucErrorMessage([ErrorNumber [, tHandle]])

Parameters

ErrorNumber

Optional. When ErrorNumber is specified, the text of the corresponding error message is returned. If this argument is omitted, or has a value of 0, then the error message associated with the most recent transaction is returned. ErrorNumber can be either a value that you have configured, or one of the pre-defined error constants.

tHandle

Optional. Each thread has its own definitions, and keeps separate track of its errors. By specifying this argument, you can select which thread to check for an error. If no thread is specified, the default thread is implied. If you are calling ucErrorMessage from a centralized error handling callback, then tHandle should generally not be omitted.

In C# or the class implementation of uCalc FMP for .NET, uCalcNET.uCalcNET.ucErrorMessage() should be used in error handling callbacks, whereas outside of error handling routines, the class member version of ucErrorMessage() should be used (for instance uc.ucErrorMessage() in the demo).

New or enhanced in version 2.96

• uc_Err_Dynamically_Defined is new. It is used by ucRaiseErrorMessage.

New or enhanced in version 2.9+

• There are additional messages, including things like Overflow, Underflow, and more.
• The syntax for ucErrorMessage is more uniform across various compilers.

Issues for users migrating from version 2.0

• Error messages were reorganized. Some messages were removed, and others added. The numbering is different.
• In version 2.0, the name of the offending item (such as a function or variable name) was returned with ucErrorData(0). Now you should use an error handling callback routine along with ucErrSymbol() to achieve that functionality.
