The %connect() function requests a connection between two sockets.
code = %connect(fd, addr.family, host, port)
| fd | File descriptor of the local socket returned by a previous call to the FlashBASIC C function %socket(). |
| addr.family | Specifies the addressing scheme used by the protocol. This field must match the address family used when creating the socket. Valid values are defined in the include file: dm,bp,unix.h socket.h. |
| host | Destination host name. The string must be known to the local network manager. Internally, this calls getaddrinfo to resolve the remote host. |
| port | Port number on the distant host. Legal value for this field depends on the protocol. On TCP/IP, for example, valid port numbers are from 1024 to 32767. |
To compile successfully, the statement cfunction socket.builtin must be included in the source code.
Upon successful completion, a value of 0 is returned in code. In case of error, a value of -1 is returned and the system(0) function is set to the value of errno.
The connection is closed when the socket is closed.
