# pcap\_close(3)

close a capture device or savefile

## NAME

pcap\_close - close a capture device or savefile

## SYNOPSIS

```
#include <pcap/pcap.h>
```

**void pcap\_close(pcap\_t \*p);**

## DESCRIPTION

**pcap\_close**() closes the files associated with *p* and deallocates resources. This means that, for example, if *p* refers to a savefile that was opened with **pcap\_fopen\_offline**() or **pcap\_fopen\_offline\_with\_tstamp\_precision**(), the stream provided to the routine will be closed unless it is **stdin**.

## SEE ALSO
