Record Transfer Interface
(BSCRTI)
Note
In this document, the term “Freeway” can mean either a Freeway
server or an embedded ICP. For the embedded ICP, also refer to
the user’s guide for your ICP and operating system (for example,
the ICP2432 User’s Guide for OpenVMS Alpha (DLITE Interface)).
The Record Transfer Interface consists of a set of procedure calls that are used by the
BSC File Transfer Interface (BSCFTI) to send and receive records from the ICP. You may
use these calls from your own application by linking your program with the modules
BSCRTI.OBJ, BSCFWY.OBJ, and ICPDLI.OBJ.
The Record Transfer Interface requires more programming in the user application than
the File Transfer Interface. The application has total responsibility for file access, record
blocking, insertion of applicable record separators or count characters, and handling of
errors or unexpected responses.
This chapter describes each BSCRTI procedure, and its associated parameters and
return codes. See Table 5–2 on page 95 for a complete list of the BSC File Transfer pro-
gram error codes.
