   20 .TH PCAP_CAN_SET_RFMON 3PCAP "31 July 2016"
   21 .SH NAME
   22 pcap_can_set_rfmon \- check whether monitor mode can be set for a
   23 not-yet-activated capture handle
   24 .SH SYNOPSIS
   25 .nf
   26 .ft B
   27 #include <pcap/pcap.h>
   28 .LP
   29 .ft B

   33 .SH DESCRIPTION
   34 .B pcap_can_set_rfmon()
   35 checks whether monitor mode could be set on a capture handle when
   36 the handle is activated.
   37 .SH RETURN VALUE
   38 .B pcap_can_set_rfmon()
   39 returns 0 if monitor mode could not be set,
   40 1 if monitor mode could be set, and a negative value on error.
   41 A negative return value indicates what error condition occurred.
   42 The possible error values are:
   43 .TP
   44 .B PCAP_ERROR_NO_SUCH_DEVICE
   45 The capture source specified when the handle was created doesn't
   46 exist.
   47 .TP
   48 .B PCAP_ERROR_PERM_DENIED
   49 The process doesn't have permission to check whether monitor mode
   50 could be supported.
   51 .TP
   52 .B PCAP_ERROR_ACTIVATED
   53 The capture handle has already been activated.
   54 .TP
   55 .B PCAP_ERROR
   56 Another error occurred.
   57 .B pcap_geterr(3PCAP)
   58 or
   59 .B \%pcap_perror(3PCAP)
   60 may be called with
   61 .I p
   62 as an argument to fetch or display a message describing the error.
   63 .LP
   64 Additional error codes may be added in the future; a program should
   65 check for 0, 1, and negative, return codes, and treat all negative
   66 return codes as errors.
   67 .B pcap_statustostr(3PCAP)
   68 can be called, with a warning or error code as an argument, to fetch a
   69 message describing the warning or error code.
