There are a lot of inconsistencies in the statements in your last post and you didn't answer most of my questions. Let me try once more:
  1. What is the function prototype for your function?
  2. What do you want your function to return (an integer or a string)? Your example said it should return "78" (which is a string), but you said you could use atoi() which returns an int???
  3. If you want your function to return one value, why are you passing it more than one string?
  4. What errors do you want to detect?
  5. How do you want to report errors? (Special return values, changing errno, diagnostics printed to stderr, ...)
  6. Have you read the man page for atoi()? If you have, why is the ".text" a concern?
the reason i didn't answer the questions last time is that it turns out that there were no [or few] errors to be checked for.

the prototype might be something like:

Code:
int returnInt(char *)

which would be called in a loop when the program has determined how many "xyz.NN.text" files there were. the "text" files are in each users ~/share/voice/" directory. each text file contains text of some kind. this text can be from one word such as "Hello" to possibly 50 words. (I have not tested the limit of the GTK+ 3.0 "label" widget.

the function should return the intereger vale of whatever string vale i can extract. foo.9.text would be stripped to the string "9" and one final line could easily return and int 9.

[!!] i just discovered that

Code:
 nptr = "89.text";

returns int 89. nothing in the man atoi page indicated that.

Nevertheless, if there is a way of [[easily]] stripping of the "text" i would be much obliged for some example code. ---or maybe find the src for atoi. Anyway, thanks for the clue.

PS: Homework!? I was part of the crew who turned v6 UNIX to v7 UNIX. I'm rusty but still at it ... .
