I have read the data from the pcap file in to a buffer. Now I need to search for a pattern in the data from pcap stored in buffer. Could anyone please tell me a c function that can be used to search for the pattern? For example the data may contain 00 0f a2 ee cd 34 23 78 00 and I need a c function to search for cd34.
You can try memmem() [GNU extension] const char pattern[] = { 0xcd, 0x34 }; memmem(buf, buflen, pattern, sizeof(pattern)); ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
