Command to get linestyle

Hi,

I would like to get the line style of 2d entity inside a sketch what are all the possible API's available to get the line style, whether it is

PRO_LINESTYLE_SOLID PRO_LINESTYLE_DOT or whatever

Existing API's are not stable ProCurvePersistentLinestyleGet Please tell us a alternate API to get the line type.

Thanks in advance,

Regards,
