Re: [Liberty-eiffel] How return a string to the C side

[Germán Arias]

OK, I solved the problem. The string contains three integers. So,
instead return a string with the integers I use an IUP function to join
those integer in one integer, and then I return this new integer. At C
side, I use other IUP function the get the three integers (from the
returned integer) and make a char* string with these values. Then I can
return this array of chars.
