C Socket errno Codes

---

This chapter defines errno codes returned by the Cisco IOS for S/390 IUCV C socket functions. It includes these sections:

Overview

When an IUCV C socket function completes, the errno value provides additional information about the error reported. errno values are set when the return code is negative.

errno Code Table

The values of errno shown in this table are returned to C socket library applications when the return value is -1:
