Function SCIPcreateConsBasicSOCNonlinear 

pub unsafe extern "C" fn SCIPcreateConsBasicSOCNonlinear(
    scip: *mut SCIP,

    name: *const c_char,
    nvars: c_int,

) -> SCIP_RETCODE

creates and captures a nonlinear constraint that is a second-order cone constraint with all its constraint flags set to their default values

\f$\sqrt{\gamma + \sum_{i=1}^{n} (\alpha_i, (x_i + \beta_i))^2} \leq \alpha_{n+1}, (x_{n+1}+\beta_{n+1})\f$

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