## NAME

pskc\_get\_key\_policy\_numberoftransactions - API function

## SYNOPSIS

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

**uint64\_t pskc\_get\_key\_policy\_numberoftransactions(pskc\_key\_t \*** *key***, int \*** *present***);**

## ARGUMENTS

  output variable indicating whether data was provided or not.

## DESCRIPTION

Get the PSKC KeyPackage Key Policy NumberOfTransactions value.  The value in this element indicates the maximum number of times a key carried within the PSKC document can be used by an application after having received it.  When this element is omitted, there is no restriction regarding the number of times a key can be used.

Note that while the PSKC specification uses the XML data type "nonNegativeInteger" for this variable, this implementation restricts the size of the value to 64-bit integers.

If *present* is non-NULL, it will be 0 if the Counter field is not present or 1 if it was present.

## RETURNS
