remove bogus char

[viba]

Hi all,

I am trying a strncpy (tempstr,srcstrng,sizeof(tempstr));

where in char tempstr[200];
char srcstng[100];

in this case in the destination array many free mem is present & when i retrive tempstr i get bogus char appended with the string .

i have tried using strncpy (tempstr,srcstrng,strlen(srcstrng));

but still the problem continues .Can someone help me with this please ?

thanks ,
Viba

and srcstring is nul terminated as a proper C string? Can you, before copying the string over, confirm that the last character is the NUL character?

You have to be careful wirth strncpy(). If it encounters a null terminator before the charcter copy limit is reached, it copies the null terminator and quits. Other wise it just quits at the character copy limit leaving the destination with no null terminator. Your destination, in this case, is a string of characters of indefinite length. It will include everything in memory until a binary zero is encountered. Hence the bogus characters.

Better post your code. I would like to see how you are calling this function.
