syntax:

Clib.errno

description:

The property errno stores diagnostic message information when a function fails to execute correctly. Many functions in the Clib and SElib objects set errno to non-zero in case of error to provide information about the error that is more specific. ScriptEase implements errno as a macro to the internal function _errno(). This property can be accessed with Clib.perror() or Clib.strerror().

Clib.perror()
