PCAP_CAN_SET_RFMON(3PCAP) PCAP_CAN_SET_RFMON(3PCAP)
pcap_can_set_rfmon - check whether monitor mode can be set for a
not-yet-activated capture handle
#include <pcap/pcap.h>
int pcap_can_set_rfmon(pcap_t *p);
pcap_can_set_rfmon() checks whether monitor mode could be set on
a capture handle when the handle is activated.
pcap_can_set_rfmon() returns 0 if monitor mode could not be set,
1 if monitor mode could be set, and a negative value on error. A
negative return value indicates what error condition occurred.
The possible error values are:
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 check whether
monitor mode could be supported.
PCAP_ERROR_ACTIVATED
The capture handle has already been activated.
PCAP_ERROR
Another error occurred. pcap_geterr(3PCAP) or
pcap_perror(3PCAP) may be called with p as an argument to
fetch or display a message describing the error.
Additional error codes may be added in the future; a program
should check for 0, 1, and negative, return codes, and treat 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.
