to start thread after a certain amount of time, add delay option in the json file in microseconds --- V3: make use of wait_before_start to store the delay param specified in task property V2: this is an update on the previous patch, handling the comments - make delay as usec instead of using the nano sec structure - make thread delay & spacing mutually exclusive this patch is based on 17be4548 --- src/rt-app.c | 5 +++-- src/rt-app_parse_config.c | 3 +++ 2 files changed, 6 insertions(+), 2 deletions(-)
