Function generate_master 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn generate_master(
    network: *const c_char,
    length: *const c_char,
    passphrase: *const c_char,
) -> *mut c_char

Generates a mnemonic phrase of a given length. Defaults to 24 words. A master xprv is created from the mnemonic and passphrase.

• OUTPUT

MasterKey {
  fingerprint: String,
  mnemonic: String,
  xprv: String,
}

Safety

• This function is unsafe because it dereferences and a returns raw pointer.
• ENSURE that output is passed into cstring_free(ptr: *mut c_char) after use.
