void TCLAP::StdOutput::failure | ( | CmdLineInterface & | c,
|  | ArgException & | e |
| ) |  |  | `[inline, virtual]`

Prints (to stderr) an error message, short usage Can be overridden to produce alternative behavior.

Parameters:

  | c | - The CmdLine object the output is generated for.
  | e | - The ArgException that caused the failure.

Implements TCLAP::CmdLineOutput.

|  | const std::string & | s,
|  | int | maxWidth,
|  | int | indentSpaces,
|  | int | secondLineOffset |
| ) |  |  | const`[inline, protected]`

This function inserts line breaks and indents long strings according the params input.

It will only break lines at spaces, commas and pipes.

Parameters:

  | os | - The stream to be printed to.
  | s | - The string to be printed.
  | maxWidth | - The maxWidth allowed for the output line.
  | indentSpaces | - The number of spaces to indent the first line.
  | secondLineOffset | - The number of spaces to indent the second and all subsequent lines in addition to indentSpaces.
