3  –  Return Values

    nonzero            According to the LC_CTYPE category of the
                       current program locale, the string specified
                       as a property argument is the name of an
                       existing character mapping. The value returned
                       can be used in a call to the towctrans
                       function.
    0                  Indicates an error. The property argument
                       does not identify a character mapping in the
                       current program's locale.
