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(3) \&.
DESCRIPTION
Sends a vector of buffers to the destination. This uses sendmsg(3) when available to perform a gathered write. If IOV_MAX is reached, a fallback will be used.
