Subject: Return action state on SIMIX_req_host_execution_wait().
X-Git-Tag: v3.6_beta2~410
X-Git-Url: http://info.iut-bm.univ-fcomte.fr/pub/gitweb/simgrid.git/commitdiff_plain/37c3311044fe215372be2a6075b82dba65ac5b1a

Return action state on SIMIX_req_host_execution_wait().
This avoids a call to SIMIX_req_host_execution_get_state right afterwards.
