Detailed Description

Error reporting interface.

This module defines the return status type. It also provides tools for interactions with status values, such as converting them to a string.

Enumeration Type Documentation

enum EpidStatus

Return status for SDK functions.

Convention for status values is as follows:

  • Zero indicates "success"
  • Any positive number indicates "success with status"
  • Any negative number indicates "failure"
Enumerator
kEpidNoErr 

no error

kEpidSigValid 

Signature is valid.

kEpidSigInvalid 

Signature is invalid.

kEpidSigRevokedInGroupRl
