Ken Owen's solution to the foxtrot exercise (in Perl) used the function split which made me think such a function would be useful in tiny-c. I modified my graph.tc program (which involves date / amount data separated by a space) to use such a split function.

split takes 3 arguments:

split int t(0);char s(0),delim(0) [ ]

Note: When "arrays" are arguments to a function, you always use 0 in the parentheses even though what you pass to it will usually have a non-zero value in the array declaration.

If the string s had "2009/11/22 50 2009/12/29 25 " and the string delim had " " you would get

t(0)="2009/11/22"
t(1)="50"
t(2)="2009/12/29"
t(3)="25"

Here's a program that takes date / amount data and produces a horizontal bar graph of it.

Here's what it generates.
