What is method Descriptor/signature for byte[] byte array using JNI?

Question

My JAVA class code snippet. I want to access getReg_chal() method from my C file using JNI:

public byte[] getReg_chal() {
    return reg_chal;
}

My C file doing some jni operation:

mid = (*env)->GetMethodID(env, info, "getReg_chal()", "([B)V");

mid = (*env)->GetMethodID(env, info, "getReg_chal()", ***);

I want to know the method descriptor for my byte[]. Writing "({B)V" gives me method not found error. What would I fill in ***? Please help me. Thanks in advance.
