Configuration
void Z3_API Z3_global_param_set (__in Z3_string param_id, __in Z3_string param_value)
 Set a global (or module) parameter. This setting is shared by all Z3 contexts.
void Z3_API Z3_global_param_reset_all (void)
 Restore the value of all global (and module) parameters. This command will not affect already created objects (such as tactics and solvers).
Z3_bool Z3_API Z3_global_param_get (__in Z3_string param_id, __out Z3_string_ptr param_value)
 Get a global (or module) parameter.
Create configuration
Z3_config Z3_API Z3_mk_config (void)
 Create a configuration object for the Z3 context object.
void Z3_API Z3_del_config (__in Z3_config c)
 Delete the given configuration object.
void Z3_API Z3_set_param_value (__in Z3_config c, __in Z3_string param_id, __in Z3_string param_value)

Create context
Z3_context Z3_API Z3_mk_context (__in Z3_config c)
 Create a context using the given configuration.
Z3_context Z3_API Z3_mk_context_rc (__in 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.
void Z3_API Z3_del_context (__in Z3_context c)

void Z3_API Z3_inc_ref (__in Z3_context c, __in Z3_ast a)

void Z3_API Z3_dec_ref (__in Z3_context c, __in Z3_ast a)
 Decrement the reference counter of the given AST. The context c should have been created using Z3_mk_context_rc. This function is a NOOP if c was created using Z3_mk_context.
void Z3_API Z3_update_param_value (__in Z3_context c, __in Z3_string param_id, __in Z3_string param_value)
