Question

null character not displaying

  • June 29, 2010

I am building an ascii data stream and writing it out to a text file.

Each line of text needs to be terminated with the null character which I am appending to within the ACL via :
text_line=string . chr(0);

When I open the text file in Notepad++, and view symbols it is not displaying the NUL symbol; Other ascii symbols appear ok.

Am I using the correct ACL syntax ? Do I need to provide an extra parameter when writing out to the file ?

Regards,

Andy

    Try building your string like this:

    text_line = pack("a*x", string)

    Also, make sure you include a "b" in the string for the "access"
    parameter to the open() function and use the write() function to write
    the data to the file.
