readlink null termination problem

Tue Jan 6 00:43:00 GMT 2004

I was having a problem with mkcramfs on cygwin creating symbolic links 
for the compressed linux filesystem.
mkcramfs uses malloc to allocate a buffer that it sends to the readlink function in cygwin path.cc
That function uses memcpy to do a copy of the link into a buffer.
Neither mkcramfs or readlink is null-terminating the string representing the link.
Probably both are at fault. I have fixed my problem by zeroing the buffer in mkcramfs
 before calling readlink, but it would probably be beneficial if readlink terminates
 the returned string, if there is room.
