Select listens into an infinite loop causing CPU usage to exceed 100%

msg · December 20, 2019, 3:41am

My goal is: [The return value of select is always 0]
My actions are: [The mongoose6.14 library that I call is packaged as a * .a file. The program runs normally on the mobile terminal of the iOS mobile phone. The program does not exit, but just turns off the screen and then opens to continue the operation. The return value of select is always 1 (, and the CPU usage exceeds 100%.Phone hot]
The result I see is: [2019-12-20 10:43:48.473366+0800 KouyuDemo[268:8783] ===>init params:{ "appKey" : "17KouyuTestAppKey", "secretKey" : "", "provision" : "\/var\/containers\/Bundle\/Application\/CB5F3EB7-6D30-404D-9C71-8A700439278D\/KouyuDemo.app\/STKouyuEngine.bundle\/skegn.provision", "cloud" : { "enable" : 1, "server" : "ws:\/\/192.168.0.12:8090" }, "sdkLog" : { "enable" : 1, "level" : 3, "output" : "\/var\/mobile\/Containers\/Data\/Application\/22D88199-3B67-4BEC-85B6-17A066590041\/Documents\/sdkLog.txt" } } 2019-12-20 10:43:48.484564+0800 KouyuDemo[268:8783] 初始化引擎是否成功？ - 1 select == num_ev= 0, timeout=1 2019-12-20 10:43:48.633177+0800 KouyuDemo[268:8644] [Gyro] Manually set gyro-interrupt-calibration to 200 select == num_ev= 0, timeout=1 select == num_ev= 0, timeout=1 select == num_ev= 0, timeout=1 ....... select == num_ev= 0, timeout=1 2019-12-20 10:43:55.281862+0800 KouyuDemo[268:8644] start params:{ "app" : { "userId" : "user-id" }, "soundIntensityEnable" : 1, "audio" : { "sampleBytes" : 2, "max_ogg_delay" : 9600, "channel" : 1, "sampleRate" : 16000, "audioType" : "wav" }, "request" : { "realtime_feedback" : 1, "mode" : "school", "phoneme_output" : 1, "dict_type" : "KK", "qType" : 0, "refText" : "You mean a lot to me.", "coreType" : "sent.eval" }, "coreProvideType" : "cloud" } select == num_ev= 1, timeout=1 send_buf========\200X-\200===nc->send_buf.len======146 send_buf========\200X-\200===nc->send_buf.len======171 send_buf========\200X-\200===nc->send_buf.len======204 send_buf========\200X-\200===nc->send_buf.len======206 send_buf========\260\271\206===nc->send_buf.len======249 select == num_ev= 1, timeout=3 send_buf========@\325\346\202===nc->send_buf.len======33 select == num_ev= 1, timeout=3 send_buf========cv===nc->send_buf.len======249
