NAME

mongoc_socket_sendv() - 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.

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.

RETURNS
