bio_edit function variables

In our morning class on Thursday February 3, 2011 we discussed the bio_edit function. Fardad explained what each variable represents and drew a diagram on the board. I created an image of that diagram using MS Paint below. Hopefully this diagram will be useful in understanding the variables and what they mean.


Variables:

- row - represents the rows of the screen for the field where 0 is the top row.

- col - represents the starting column of the field where 0 is the left most column.

- maxdatalen - contains the maximum length of the string (str).

- fieldlen - contains the length of the field where editing is to be performed
( visible area of str)

- *offset - points to an integer holding the index of the first character in the string (str).

- *curpos - points to an integer holding the position of the cursor.
