lp_var_get(+Handle, +Var, ++What, -Value)

   Obtain information for an individual solver problem variable Var.

Arguments
   Handle              Handle to a solver state
   Var                 A solver problem variable for Handle
   What                Specification for information wanted (atom)
   Value               Returned value of What

Type
   library(eplex)

Description

   Retrieve information about the (logically) most recent solver state and
   results related to a particular variable, for the solver state
   represented by Handle. Fails if no solution has been computed yet. What
   can take the same values as those in eplex_var_get/3.

Exceptions
     4 --- Handle is not instantiated.
     5 --- Handle is not a compound term.
     6 --- What is not a valid value.
     6 --- Var is not a problem variable for Handle.
     6 --- What is unavailable; the information was not requested at solver setup.
    40 --- Handle not valid: solver state had been destroyed by cleanup
