# pskc\_set\_device\_issueno(3)

API function

## NAME

pskc\_set\_device\_issueno - API function

## SYNOPSIS

**#include \<pskc.h\>**

**void pskc\_set\_device\_issueno(pskc\_key\_t \*** *key***, const char \*** *issueno***);**

## ARGUMENTS

- pskc\_key\_t \* key

  a **pskc\_key\_t** handle from, e.g., **pskc\_add\_keypackage()**.

- const char \* issueno

  a string with issue number to set.

## DESCRIPTION

Set the PSKC KeyPackage DeviceInfo IssueNo value.  This element contains the issue number in case there are devices with the same serial number so that they can be distinguished by different issue numbers.

The pointer is stored in *container*, not a copy of the data, so you must not deallocate the data before another call to this function or the last call to any function using *container*.

## SINCE

2\.2.0
