Module Name: src
Committed By: jmmv
Date: Wed Jul 14 21:47:06 UTC 2010
Modified Files:
src/tests/kernel: Makefile
Added Files:
src/tests/kernel: t_sigaction.c
Log Message:
Add a couple of simple tests for sigaction(2): one for the case where flags
is set to 0 and the other for the case where we set SA_RESETHAND.
The latter test is intended to expose PR port-macppc/43619 and is marked as
an expected failure on such platform.
