problem.getAttribInfo

Purpose
Accesses the id number and the type information of an attribute given its name. An attribute name may be for example XPRS_ROWS. Names are case-insensitive and may or may not have the XPRS_ prefix. The id number is the constant used to identify the attribute in the C API. The type information returned will be one of the below integer constants. The function will return an id number of 0 and a type value of xpress.ParameterType.NOTDEFINED if the name is not recognized as an attribute name. Note that this will occur if the name is a control name and not an attribute name.
