source · pub type mbedtls_ssl_recv_timeout_t = Option<unsafe extern "C" fn(ctx: *mut c_void, buf: *mut c_uchar, len: usize, timeout: u32) -> c_int>;Expand description
\brief Callback type: receive data from the network, with timeout
\note That callback must block until data is received, or the timeout delay expires, or the operation is interrupted by a signal.
\param ctx Context for the receive callback (typically a file descriptor) \param buf Buffer to write the received data to \param len Length of the receive buffer \param timeout Maximum number of milliseconds to wait for data 0 means no timeout (potentially waiting forever)
\return The callback must return the number of bytes received, or a non-zero error code: \c MBEDTLS_ERR_SSL_TIMEOUT if the operation timed out, \c MBEDTLS_ERR_SSL_WANT_READ if interrupted by a signal.
\note The callback may receive fewer bytes than the length of the buffer. It must always return the number of bytes actually received and written to the buffer.
