c++ - Avoid error reading characters of string. char * -


i on several similar question, couldn't find proper solution situation. trying omp parallel loop. inside 1 of functions in parallel region, trying create m_buffer guess shared (it huge , complicated piece of code, user). 

//vector of pointers, each of points start of one-way list of free elements of same size. //the size of elements in each list  determined list's index in vector,  //namely size of element (sizeof(void) * (index + 1)). std::vector<char*> m_buffer; ... bufidx = i_element_size / sizeof(void*) - 1; ... if (m_buffer[bufidx] == nullptr) { ... } else { //comes here! }

apparently 1 thread tries allocate element inside buffer @ index of 0. attached question see buffer in debug using vs 2013. wondering if there way detect situation beside if condition.

c++ - CPP, 'X' button listener -

i'm writing cpp program, , want execute function when 'x'(shut down) button pressed. for example, have infinite loop prints same thing everytime iterates, until 'x' button pressed, , want execute function before process ends. is there kind of listener matter? or other solution maybe (like delaying process shut down few seconds or something)? thanks! if want execute before process ends, can register std::atexit handler. function called before process exits.

i trying share h264 encoded data gstreamer 2 processes(both based on gstreamer).after research way found use shm plugin. trying do gstreamer--->h264 encoder--->shmsink shmrc--->process1 shmrc--->process2 i able raw data videotestsrc , webcam working. h264 encoded data doesn't. test pipeline gst-launch-1.0 videotestsrc ! video/x-raw,width=640,height=480,format=yuy2 ! x264enc ! shmsink socket-path=/tmp/foo sync=true wait-for- connection=false shm-size=10000000 gst-launch-1.0 shmsrc socket-path=/tmp/foo ! avdec_h264 ! video/x- raw,width=640,height=480,framerate=25/1,format=yuy2 ! autovideosink have tried shm plugins h264 encoded data, please help iam not aware of capabilities of sink used in "autovideosink", per knowledge either need use videoconvert if format supported sink (like kmssink or ximagesink) different provided source (in case yuy2) or use videoparse if camera format supported sink. may check using gst-inspect-1...

.net - Bulk insert via Dapper is slower than inserting rows one-by-one -

i'm using dapper insert data realtime feed sql server, care performance. recently, noticed strange. out of box, if give dapper collection , insert query, fires insert statements each element. tests show can insert 1800 objects 12 fields in 1 second way (counting connection.execute(...) running time. now, didn't find batch insert functionality in dapper , implemented own (constructing parameter list , sql query). after that, found out can insert 1 batch in 3 seconds (which limited 1000 rows) (again, counting connection.execute(...) calls. so, makes batching 6 times slower sending each row in separate query. can explain me? thought people use batch operations speed process. insert time 1 second @ most. use sql server 2012 standard on local network. table i'm inserting has clustered index on primary key (which bigint field), no non-clustered indexes , triggers. can post code, there's nothing special i'm not sure why using dapper execute extension ...
