str_cpy not work - 03/19/18 20:25

hello,
i hate my 3dgs problems but must rely ask you, on my win8.1 (3dgs is installed in c:GStudio8)
why code not work for me?

Code:

#include <acknex.h>
#include <default.c>
#include <strio.c>;
STRING* srt100;
function main()
{
	level_load(NULL);
	str_cpy(srt100,"a"); // string has now empty content
}

iger Error E1515
(X) Invalid function arguments in main

P.S. i have make changes in atypes. but I have install 3dgs new and the first time, the installer told me to restart windows

Hi,
when we write

Code:

STRING *str100;

we are declaring an empty STRING pointer.

Code:

STRING *str100 = "";

Declares a STRING pointer that points to a newly created empty STRING struct. But only in global STRING pointers. For local pointers you must create it with str_create and remove it at the end.

Code:

STRING *strLocal = str_create("");
...
str_remove(strLocal);
strLocal = NULL;

Salud!

Not really, but nullifying your empty pointers is a good practice
