Expand description

\brief This function starts a SHA-384 or SHA-512 checksum calculation.

\param ctx The SHA-512 context to use. This must be initialized. \param is384 Determines which function to use. This must be either \c 0 for SHA-512, or \c 1 for SHA-384.

\note is384 must be defined accordingly to the enabled MBEDTLS_SHA384_C/MBEDTLS_SHA512_C symbols otherwise the function will return #MBEDTLS_ERR_SHA512_BAD_INPUT_DATA.

\return \c 0 on success. \return A negative error code on failure.
