NAME
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 bson_get_monotonic_time().

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.
