NAME¶
qb_ipcs_event_sendv - Send an asynchronous event message to the client.
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()
