this will run just like "cat -v filename"
if there is some control characters in the filename, such like control A, control B...
normal these control characters is not able to print out, but after program, they can be print out..
my point is, i dont know how to separate control characters with other normal character, and then how can i make is displayable..??
i tried to use iscotrl() to check the control character, but it cant separate '\n' with control characters...
anyway, thx for help
regards
