The results of this and previous strcpy() would be "undefined".

Indeed, IMHO, return the pointer to the end of the resulting string could be more useful than pointer to the beginning of the destination. This could make strcat() obsolete and make concatenate multiple strings lot faster. Return a count of the number of characters copied is equally useful. > Anand Shraddhan > > (There is a deliberate bug in the above code...) Shyan ------------------------ Yahoo!
