function posted to boost::asio::io_service::strand not executed -



function posted to boost::asio::io_service::strand not executed -

i using boost::asio in quite complex scenario , experiencing problem method posted boost::asio::io_service::strand object not executed although several worker threads on io_service running , idle.

as said, scenario complex, i'm still trying develop reasonably little repro scenario. conditions follows:

one io_service running , has work-object assigned it 4 worker threads assigned io_service (called io_service::run on each) several strand objects used post numerous different tasks in of tasks executed via strands, new tasks posted strand

the whole scheme works , stable, except 1 situation: when calling destructor of 1 of classes, posts abort handler strand (to initiate aborting in sync other taks) , waits until abort done. every 1 time in while happens, abort handler never executed (destructor called invocation of strand object).

i assume problem strand waits executing handler on same thread has been posted. , since thread waiting abort handler executed programme deadlocks.

my questions now: - assumption correct? - there way avoid situation? - how approach problem (having several async tasks running , need abort them synchronously)

thanx lot help!

m.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
