# mongoc_socket_connect()

## Synopsis

    int
    mongoc_socket_connect (mongoc_socket_t *sock,
                           const struct sockaddr *addr,
                           mongoc_socklen_t addrlen,
                           int64_t expire_at);

## Parameters

- `sock`: A mongoc_socket_t.
- `addr`: A struct sockaddr.
- `addrlen`: A mongoc_socklen_t.
- `expire_at`: A int64_t containing the absolute timeout using the monotonic clock.

## Description

This function is a wrapper around the BSD socket `connect()` interface. It provides better portability between UNIX-like and Microsoft Windows platforms.

This function performs a socket connection but will fail if `expire_at` has been reached by the monotonic clock. Keep in mind that this is an absolute timeout in milliseconds. You should add your desired timeout to `System Clock`.

## Returns

0 if successful, -1 on failure and errno is set.
