Sorry I was so grouchy.

The wait() (http://linux.die.net/man/2/wait) function monitors the state of a process, not its I/O streams. What you really want is the poll() (http://linux.die.net/man/2/poll) or select()...

I think you need to spend some time tracing through your algorithm. I'm not sure exactly what it is supposed to do, but I don't think it is doing what you want it to do...
(Given "HELLO", the list...

There are only a couple that I'd recommend.

First, straight from esr himself:

And another very good one, replete with great examples:...

I think you are kind of close, but you need to be careful about a couple of things.

The first problem is that the variable lookahead is local to lexan(), so your compiler should be complaining...

Agreed, but when dealing with new programmers I have learned by experience (teaching and tutoring) that debugging works best once a firm concept of what should be happing is established. Anyway...

Line 19 should read
newp = (nameval_t *) malloc( sizeof( nameval_t ) );

This is why I recommend just always using parentheses with sizeof. It always works with parens, but makes a difference...

For example, you could embed a Tcl (http://wiki.tcl.tk/) interpreter in your program (TCL or Tool Command Language is a script language). Or, you could link a Python...

You could do it something like that, but it introduces more problems than it solves:

fork() doesn't work on Windows. Even if it did, you would still need to set up some IPC to make things work...

I get the following output:
-201 -16
3.141

Did you compile with gcc -traditional-cpp ?


The printf statement just uses as few characters as needed to work.
4. floating point number

If you are using the GNU tools, you can say:
gmake -n -p
to print the internal database used to compile without actually compiling anything.

Also, you can get the GNU compiler to give you...

Or you could just use the strspn() function:
if (strspn( dnaStr, "AaTtCcGg" ) < strlen( dnaStr )) puts( "error in DNA" );

Yes, yes, exactly. Thank you.

I've nothing against memcpy(). Just using it improperly.

Best answer is, don't do that.

You are playing with undefined behavior. For any single variable, there should be a maximum of one pre/post increment/decrement operator. Otherwise your results may...
