Behind Keyboard		[947] possible bug with strCopyLen - posted: 2011-12-02 18:37:36
when is was printing the information copied i keept getting some jibberish, like it was reading past the mem used for that string. so i made this to test and as i suspected, seems like strcopylen doesn´t add 0 at the end of the buffer


Code:
program WIN32CUI 'Test';

#include 'ch.zir';
#include 'fileio.zir';
#include 'strings.zir';

char curVar[25], server_name[25];

strCopyLen(@curVar, 'testing a thing here', 20);
strCopyLen(@curVar, 'name', 4);


strLen(@curVar);
strCopyLen(@server_name,@curVar, eax);
print('curVar= ',@curVar, '\r\n');

wait_key(nil);

ExitProcess(0);


prints


Code:
curVar= namening a thing here

Code:
strCopyLen(@curVar, 'testing a thing here', 21);
strCopyLen(@curVar, 'name', 5);


this will output

curvar = name;

just to note that 'const strings' have an auto null byte, so if you want to append that too you need to add the extra 1 char size.

a sample scenario:

var1 = 'testing';

Code:
strCopyLen(@var1, 'post', 4);


var1 will now equal "posting"

but....

Code:
strCopyLen(@var1, 'post', 5);


var1 will equal "post"

hope this helps.
