I want to store a raw hexdump into a .pcap file instead of a .txt file. Is there any header/format that is available which i can use, so that the raw hexdump along with the special header/format can be read as a pcap file by Wireshark.

Basically, i need the backend or functionality of the "Import from hexdump" option so that i can use it on a hexdump file to open it as a pcap file. Any help is much appreciated.

You could easily whip something together using this information on the pcap file format.

Have a look at Text2pcap which does exactly that, and more besides.

Is it possible to use this in a C code?

You can either call text2pcap directly from your C application, or, if you observe the licence for text2pcap (GPL v2.0 or later) then re-use the code in text2pcap to achieve the same but note that it has dependencies on other parts of the wireshark suite.
