Function olm_sys::olm_pk_decrypt

pub unsafe extern "C" fn olm_pk_decrypt(
    decryption: *mut OlmPkDecryption, 
    ephemeral_key: *const c_void, 
    ephemeral_key_length: usize, 
    mac: *const c_void,

) -> usize

Decrypt a ciphertext. The input ciphertext buffer is destroyed. See the olm_pk_encrypt function for descriptions of the ephemeral_key and mac arguments. Returns the length of the plaintext on success. Returns olm_error() on failure. If the plaintext buffer is too small then olm_pk_encryption_last_error() will be “OUTPUT_BUFFER_TOO_SMALL”.
