MONGOC_SOCKET_SENDV(3)

NAME
mongoc_socket_sendv - mongoc_socket_sendv()

SYNOPSIS

ssize_t
mongoc_socket_sendv (mongoc_socket_t *sock,
                     mongoc_iovec_t *iov,
                     size_t iovcnt,
                     int64_t expire_at);

PARAMETERS

•   sock: A mongoc_socket_t.

•   iov: A mongoc_iovec_t.

•   iovcnt: A size_t containing the number of elements in iov.

•   expire_at: A int64_t with absolute timeout in monotonic time. The monotonic clock is in microseconds and can be fetched using System Clock.

DESCRIPTION

Sends a vector of buffers to the destination. This uses sendmsg() when available to perform a gathered write. If IOV_MAX is reached, a fallback will be used.

RETURNS
