[ace-users] I write a function named nstrsncpy

[Douglas C. Schmidt]

Hi Kevin,

   Why are you posting this message to the ACE mailing list?  It has
nothing to do with ACE.

Thanks,

        Doug

>It copy char array 'src' to char array 'dst'. If the length of src is >= maxlen, It just copy maxlen-1 bytes. It will add '\0' to dst at the end, so it's safe for the caller.
