SYNOPSIS¶

#include <qb/qbipcs.h>

ssize_t qb_ipcs_event_sendv(


    qb_ipcs_connection_t   *c,        /* connection instance */
    /*


     * the iovec struct that points to the message to send


     */


    const struct iovec     *iov,


    size_t                  iov_len   /* the number of iovecs. */
);

PARAMS¶

c connection instance

iov the iovec struct that points to the message to send

iov_len the number of iovecs.

DESCRIPTION¶

RETURN VALUE¶

size sent or -errno for errors

NOTE¶

When send returns -EMSGSIZE, this means the msg is too large and will never succeed. To determine the max msg size a client can be sent, use qb_ipcs_connection_get_buffer_size()
