| 23 | .SH NAME |
| 24 | pcap_file \- get the standard I/O stream for a savefile being read |
| 25 | .SH SYNOPSIS |
| 26 | .nf |
| 27 | .ft B |
| 28 | #include <pcap/pcap.h> |
| 29 | .ft |
| 30 | .LP |
| 31 | .ft B |

| 35 | .SH DESCRIPTION |
| 36 | .B pcap_file() |
| 37 | returns the standard I/O stream of the ``savefile,'' if a ``savefile'' |
| 38 | was opened with |
| 39 | .BR pcap_open_offline() , |
| 40 | or NULL, if a network device was opened with |
| 41 | .B pcap_create() |
| 42 | and |
| 43 | .BR pcap_activate() , |
| 44 | or with |
| 45 | .BR pcap_open_live() . |
| 46 | .PP |
| 47 | Note that the Packet Capture library is usually built with large file |
| 48 | support, so the standard I/O stream of the ``savefile'' might refer to |
| 49 | a file larger than 2 gigabytes; applications that use |
| 50 | .B pcap_file() |
| 51 | should, if possible, use calls that support large files on the return |
| 52 | value of |
| 53 | .B pcap_file() |
| 54 | or the value returned by |
| 55 | .B fileno() |
| 56 | when passed the return value of |
| 57 | .BR pcap_file() . |
