BN_KRONECKER(3)            Library Functions Manual            BN_KRONECKER(3)

NAME
     BN_kronecker - Kronecker symbol

SYNOPSIS
     #include <openssl/bn.h>

     int
     BN_kronecker(const BIGNUM *a, const BIGNUM *b, BN_CTX *ctx);

DESCRIPTION
     BN_kronecker() computes the Kronecker symbol (a | b), which generalizes
     the Legendre and Jacobi symbols for arbitrary integer numbers b.

RETURN VALUES
     BN_kronecker() returns -1, 0, or 1 in case of success or -2 on error.
