c - How to gracefully make a blocking pthread exit from the main thread? -

i have pthread indefinite polling on file descriptors, negative timeout parameter. from main thread, able indicate polling thread should exit. i did research , found following approaches: use pthread_cancel(): discouraged might lead unintended consequences of not clearing held resources or mutexes use variable flag , set in main thread. polling thread checks flag every iteration , if set, exits calling pthread_exit(). approach won't work because polling thread doesn't loop, blocks indefinitely, waiting on file descriptors. can suggest elegant solution problem ? thanks! asm you can create anonymous pipe pipe(2) , have file-descriptor-watching thread add read end polled file descriptors, exiting when file descriptor reports eof. main thread closes write end when wants thread exit.

c++ - GLFW and GLEW - Missing .libs -

-
i've not been having best day today. new opengl , c++ libraries in general. don't know how link libraries msvs2015, decide tutorial on how link opengl libraries glfw , glew. i've read on 6 different tutorials on last 8 hours, , tell me link "lib" folder. folder empty in glew 2.0.0 download, , missing in glfw 3.2.1 download. confused, read online there supposed .lib files in there. searched both downloads "*.lib", thinking have been moved in update , found nothing ".lib" extension. did same ".dll" , nothing found. i'm downloading these libraries from: http://www.glfw.org/ http://glew.sourceforge.net/ am downloading wrong source or tutorials old(the tutorials found stated latest versions glew <1.9 , glfw ~2)? if need more information(setup, pictures...) ask. i needed download binaries system instead of source, or build cmake or other building program. oh well, guess learned :/
