Hi

I have read the code
http://www.k-otik.com/exploits/20041020.HOD-ms04032-emf-expl2.c.php but
does not understand \x...... portion. An example:

unsigned char emfheader[] =
"\x01\x00\x00\x00\x40\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00"


May someone advise what does hex coding means? Any reference site for
good explanation?


Thank a million
