This topic describes the FTP Client Application Programming Interface (API) to the z/OS® FTP client.

The interface also enables the user program to retrieve output that includes the messages from the client, replies from the FTP server, and other data generated as the result of the request. The interface requires the use of an FTP Client Application Interface (FCAI) control block that is created by the user program (see FTP Client Application Interface (FCAI) control block). The FCAI is a parameter on all calls to the interface and it is used to pass information between the interface and the user program. The following topics are included in this topic:
