MONGOC_SOCKET_SEND(3)

SYNOPSIS

ssize_t
mongoc_socket_send (mongoc_socket_t *sock,


                    const void *buf,


                    size_t buflen,


                    int64_t expire_at);

PARAMETERS

sock: A mongoc_socket_t <>.
buf: A buffer to send.
buflen: A size_t with the number of bytes in buf.
expire_at: A int64_t with an absolute timeout for the operation or 0. The timeout is in monotonic time using microseconds. You can retrieve the current monotonic time with System Clock <https://www.mongoc.org/libbson/current/bson_get_monotonic_time.html>.

DESCRIPTION

Sends buflen bytes in buf to the destination. If a timeout expired, the number of bytes sent will be returned or -1 if no bytes were sent.

RETURNS

-1 on failure and errno is set, or the number of bytes sent.
