Function s2n_quic::provider::tls::default::ffi::s2n_recv

pub unsafe extern "C" fn s2n_recv(
    conn: *mut s2n_connection,
    buf: *mut c_void,
    size: isize,
    blocked: *mut u32
) -> isize

Decrypts and reads *size to buf data from the associated connection.

@note Unlike OpenSSL, repeated calls to s2n_recv should not duplicate the original parameters, but should update buf and size per the indication of size read.

See the following example for guidance on calling s2n_recv(): https://github.com/aws/s2n-tls/blob/main/docs/examples/s2n_recv.c

@param conn A pointer to the s2n_connection object @param buf A pointer to a buffer that s2n will place read data into. @param size Size of buf @param blocked A pointer which will be set to the blocked status if an S2N_ERR_T_BLOCKED error is returned. @returns The number of bytes read on success. 0 if the connection was shutdown by the peer. S2N_FAILURE on failure.
