# pskc\_set\_key\_id(3)

API function

## NAME

pskc\_set\_key\_id - API function

## SYNOPSIS

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

**void pskc\_set\_key\_id(pskc\_key\_t \*** *key***, const char \*** *keyid***);**

## ARGUMENTS

- pskc\_key\_t \* key

  a **pskc\_key\_t** handle, from **pskc\_get\_keypackage()**.

- const char \* keyid

  the key identity string to set.

## DESCRIPTION

Set the PSKC KeyPackage Key Id attribute value.  It is a syntax error for this attribute to not be available.

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*.
