[Libsysio-commit] HEAD: libsysio/src getdirentries.c

[Lee W. <lw...@us...>]

Update of /cvsroot/libsysio/libsysio/src
In directory sc8-pr-cvs6.sourceforge.net:/tmp/cvs-serv11638

Modified Files:
	getdirentries.c 
Log Message:


The getdirentries function was converted to blindly convert the
64-bit directory entry structure. When the native format is
the same layout this resulted in a memcpy of the name in overlapping
regions. That's a no-no. Changed, now, to use memmove, which allows
overlapping copies.
