Win32 Specific. Sends a raw packet. This function allows to send a raw packet to the network. p is the interface that will be used to send the packet, buf contains the data of the packet to send (including the various protocol headers), size is the dimension of the buffer pointed by buf, i.e. the size of the packet to send. The MAC CRC doesn't need to be included, because it is transparently calculated and added by the network interface driver. The return value is 0 if the packet is succesfully sent, -1 otherwise.

Win32 Specific. Sets the size of the kernel buffer associated with an adapter. dim specifies the size of the buffer in bytes. The return value is 0 when the call succeeds, -1 otherwise. If an old buffer was already created with a previous call to pcap_setbuff(), it is deleted and its content is discarded. pcap_open_live() creates a 1 MByte buffer by default.

Win32 Specific. Sets the minumum amount of data received by the kernel in a single call. pcap_setmintocopy() changes the minimum amount of data in the kernel buffer that causes a read from the application to return (unless the timeout expires). If the value of size is large, the kernel is forced to wait the arrival of several packets before copying the data to the user. This guarantees a low number of system calls, i.e. low processor usage, and is a good setting for applications like packet-sniffers and protocol analyzers. Vice versa, in presence of a small value for this variable, the kernel will copy the packets as soon as the application is ready to receive them. This is useful for real time applications that need the best responsiveness from the kernel.

Win32 Specific. Sets the working mode of the interface p to mode. Valid values for mode are MODE_CAPT (default capture mode) and MODE_STAT (statistical mode). See the tutorial "Gathering Statistics on the network traffic " for details about statistical mode. Definition at line 749 of file Pcap-win32.c. References PacketSetMode(), and snprintf. |
