[Ltp-cvs] ltp/testcases/kernel/syscalls/dup2 dup203.c,1.5,1.6

[Subrata <sub...@us...>]

Update of /cvsroot/ltp/ltp/testcases/kernel/syscalls/dup2
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv25396/ltp/testcases/kernel/syscalls/dup2

Modified Files:
	dup203.c 
Log Message:
Fixes the hardcoded file descriptor in the second testcase within dup203.c . Instead of assuming file descriptor 10 is closed, the fix explicitly opens and closes a file descriptor before using it as the second argument of dup2(). We saw issues on some environments where dup2(10,10) was being called, which this fixes, by, Henry Wei <hy...@mv...>
