Re: help needed in fixing C programming error using cygwin !



Don't use strings for binary data.

Use an explicit character array, keeping track of the length yourself. 
When you send it to a device, you'll have to use read/write rather than
string operations.

It does seem convenient to use string functions, but you'll never get
around the magic nature of null characters without more trouble than it
is worth.  I went through this doing messaging across a serial port.
