Subject: Add new flag variable for checking state
X-Git-Tag: submit/tizen/20220823.092009~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5c8c344ed22f7bef17ac574b35f652458b02c4ee;p=platform%2Fcore%2Fuifw%2Ftts.git

Add new flag variable for checking state

- Issue:
The engine did not call ttse_main(), but the engine library works like
that ttse_main() was already invoked.

- Solution:
The APIs provided by engine library checks g_is_terminate flag variable
for checking whether ttse_main() is invoked or not. However,
g_is_terminate variable is for checking whether ttse_terminate() is
invoked not for checking ttse_main() invocation. So even if the engine
does not call ttse_main(), the library could not know that ttse_main()
was not invoked yet. Thus, this patch adds new flag variable for
ttse_main() invocation.
