need a C utility to search data in hex dump

[prashanth s <prbanglore () gmail com>]

Hi all,

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.

Regards,
Prashanth
