Z3_string Z3_API Z3_get_error_msg_ex (Z3_context c, Z3_error_code err)
 Return a string describing the given error code. Retained function name for backwards compatibility within v4.1. More...

 Create a context using the given configuration. More...
 
Z3_context Z3_API Z3_mk_context_rc (Z3_config c)
 Create a context using the given configuration. This function is similar to Z3_mk_context. However, in the context returned by this function, the user is responsible for managing Z3_ast reference counters. Managing reference counters is a burden and error-prone, but allows the user to use the memory more efficiently. The user must invoke Z3_inc_ref for any Z3_ast returned by Z3, and Z3_dec_ref whenever the Z3_ast is not needed anymore. This idiom is similar to the one used in BDD (binary decision diagrams) packages such as CUDD. More...

unsigned  num_terms,
Z3_ast const  terms[],
unsigned  class_ids[] 
)

Retrieve congruence class representatives for terms.

The function can be used for relying on Z3 to identify equal terms under the current set of assumptions. The array of terms and array of class identifiers should have the same length. The class identifiers are numerals that are assigned to the same value for their corresponding terms if the current context forces the terms to be equal. You cannot deduce that terms corresponding to different numerals must be all different, (especially when using non-convex theories). All implied equalities are returned by this call. This means that two terms map to the same class identifier if and only if the current context implies that they are equal.

A side-effect of the function is a satisfiability check on the assertions on the solver that is passed in. The function return Z3_L_FALSE if the current assertions are not satisfiable.
