NAME
       pcap_can_set_rfmon - check whether monitor mode can be set for a not-
       yet-activated capture handle

SYNOPSIS
       #include <pcap/pcap.h>

       int pcap_can_set_rfmon(pcap_t *p);

DESCRIPTION
       pcap_can_set_rfmon() checks whether monitor mode could be set on a
       capture handle when the handle is activated.

RETURN VALUE
       pcap_can_set_rfmon() returns 0 if monitor mode could not be set, 1 if
       monitor mode could be set, PCAP_ERROR_NO_SUCH_DEVICE if the capture
       source specified when the handle was created doesn't exist,
       PCAP_ERROR_PERM_DENIED if the process doesn't have permission to check
       whether monitor mode could be supported, PCAP_ERROR_ACTIVATED if called
       on a capture handle that has been activated, or PCAP_ERROR if an error
       occurred.  If PCAP_ERROR is returned, pcap_geterr() or pcap_perror()
       may be called with p as an argument to fetch or display the error text.
