NAME
pcap_activate - activate a capture handle
SYNOPSIS
#include <pcap/pcap.h>
int pcap_activate(pcap_t *p);
DESCRIPTION
pcap_activate() is used to activate a packet capture handle to look at
packets on the network, with the options that were set on the handle
being in effect.
RETURN VALUE
pcap_activate() returns 0 on success without warnings, a non-zero posi‐
tive value on success with warnings, and a negative value on error. A
non-zero return value indicates what warning or error condition
occurred.
The possible warning values are:
PCAP_WARNING_PROMISC_NOTSUP
Promiscuous mode was requested, but the capture source doesn't
support promiscuous mode.
PCAP_WARNING_TSTAMP_TYPE_NOTSUP
The time stamp type specified in a previous
pcap_set_tstamp_type(3PCAP) call isn't supported by the capture
source (the time stamp type is left as the default),
PCAP_WARNING
Another warning condition occurred; pcap_geterr(3PCAP) or
pcap_perror(3PCAP) may be called with p as an argument to fetch
or display a message describing the warning condition.
The possible error values are:
PCAP_ERROR_ACTIVATED
The handle has already been activated.
PCAP_ERROR_NO_SUCH_DEVICE
The capture source specified when the handle was created doesn't
exist.
PCAP_ERROR_PERM_DENIED
The process doesn't have permission to open the capture source.
PCAP_ERROR_PROMISC_PERM_DENIED
The process has permission to open the capture source but
doesn't have permission to put it into promiscuous mode.
PCAP_ERROR_RFMON_NOTSUP
Monitor mode was specified but the capture source doesn't sup‐
port monitor mode.
PCAP_ERROR_IFACE_NOT_UP
The capture source device is not up.
PCAP_ERROR
Another error occurred. pcap_geterr() or pcap_perror() may be
called with p as an argument to fetch or display a message
describing the error.
If PCAP_WARNING_PROMISC_NOTSUP, PCAP_ERROR_NO_SUCH_DEVICE, or
PCAP_ERROR_PERM_DENIED is returned, pcap_geterr() or pcap_perror() may
be called with p as an argument to fetch or display an message giving
additional details about the problem that might be useful for debugging
the problem if it's unexpected.
Additional warning and error codes may be added in the future; a pro‐
gram should check for positive, negative, and zero return codes, and
treat all positive return codes as warnings and all negative return
codes as errors. pcap_statustostr(3PCAP) can be called, with a warning
or error code as an argument, to fetch a message describing the warning
or error code.
