Function SCIPcreateConsBasicSymresack 

pub unsafe extern "C" fn SCIPcreateConsBasicSymresack(
    scip: *mut SCIP,
    cons: *mut *mut SCIP_CONS,
    name: *const c_char,
    perm: *mut c_int,
    vars: *mut *mut SCIP_VAR,
    nvars: c_int,
    ismodelcons: c_uint,
) -> SCIP_RETCODE

creates and captures a symresack constraint in its most basic variant, i.e., with all constraint flags set to their default values, which can be set afterwards using SCIPsetConsFLAGNAME() in scip.h

@see SCIPcreateConsSymresack() for the default constraint flag configuration

@note the constraint gets captured, hence at one point you have to release it using the method SCIPreleaseCons()
