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

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

Update of /cvsroot/libsysio/libsysio/src
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv13425/src

Modified Files:
	chdir.c 
Log Message:


Henry Pierce noticed that the Linux-ish support for getcwd with
a zero buffer size was gone. This had been done to make it
POSIX compatible. However, we went overboard. It only must be
applied when the passed buffer is non-null. The feature returns
with this deposit.
