int mbedtls_net_bind(mbedtls_net_context *ctx, const char *bind_ip, const char *port, int proto)
Create a receiving socket on bind_ip:port in the chosen protocol.
void mbedtls_net_free(mbedtls_net_context *ctx)
Gracefully shutdown the connection and free associated data.
int mbedtls_net_accept(mbedtls_net_context *bind_ctx, mbedtls_net_context *client_ctx, void *client_ip, size_t buf_size, size_t *ip_len)
Accept a connection from a remote client.
int mbedtls_net_set_block(mbedtls_net_context *ctx)
