Hi,
I want to change the header of some document files like pdf, ms word, libre office programatically. I know that I have to use some byte type command like putc(..) and getc(). But I don't the header size of the above mentioned file formats.I saw a list of file format at wikipedia https://en.wikipedia.org/wiki/File_format
but I can't see information about the header size. For instance, I know the header size of bmp file=54 bytes.Can some body please guide me any link which tells me this information.
