# pmFreeHighResEventResult(3)

release storage allocated for unpacked event records

## NAME

**pmFreeHighResEventResult**, **pmFreeEventResult** - release storage allocated for unpacked event records

## C SYNOPSIS

**#include \<pcp/pmapi.h\>**

**void pmFreeHighResEventResult(pmResult \*\****hrset***);**\
 **void pmFreeEventResult(pmResult\_v2 \*\****rset***);**

**cc ... -lpcp**

## DESCRIPTION

When processing event records, if [**pmUnpackHighResEventRecords**(3)](/pmUnpackHighResEventRecords/3.md) is used to unpack event records from a metric within a *pmResult* structure with a value of type **PM\_TYPE\_HIGHRES\_EVENT** then the structure returned from [**pmUnpackHighResEventRecords**(3)](/pmUnpackHighResEventRecords/3.md) is a NULL pointer terminated array of pointers to *pmResult* structures, one for each event record.

**pmFreeHighResEventResult** is a convenience method that frees all of the *pmResult* structures and the array of pointers (*hrset*).

Similarly, **pmFreeEventResult** may be used to free the *pmResult\_v2* structures and array returned from the **pmUnpackEventRecords** routine when using **PM\_TYPE\_EVENT** metrics.
