i have piece of code: function a(){ this.count = 0; } a.prototype.inc = function(){ this.count++; } var = new a(); a.inc(); var f = a.inc; f(); the last line deosn't work expected, because this object of type window . something, shouldn't - assign methods variables, in case make use of this ? when want use method argument, should omit fn(a.inc) , use regular function, , use insted following? fn(function(){ a.inc(); }); this famous "lost binding" of javascript. you have do: f = a.inc.bind(a); because if say f = a.inc; f(); then when f running, this not bound a . bound global object, window . the rule is, if a.fn() , inside of function, this bound a , if fn() or g() , when g === a.fn , inside of function, this bound global object, window . to bind this explicitly a when function invoked, have use a.inc.bind(a) if don't want use bind want use own function, that's fine too. do: function fn() { a.in...

i'm working on library port *nix android, , library uses shared memory or shm . android not have system v shm . instead uses ashmem . is aware of shim library map shm calls ashmem ? google has not been helpful. this how worked me while working similar problem of porting: instead of using shmfd = open(shm_path, o_rdwr) creating , getting file descriptor replaced with int fd = ashmem_create_region("sharedregionname", size); and used file descriptor base address: int base_address = mmap(null, size, prot_read | prot_write, map_shared, fd, 0); you can pass base_address java code native code using native function returns descriptor. android has wrapper class ashmem named memoryfile. can have in that. the following links helped me create own wrapper: http://notjustburritos.tumblr.com/post/21442138796/an-introduction-to-android-shared-memory http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/2.2_r1.1/android/os/...

there lot of such questions, going through them didn't solve problem in case. the pssetshaderresources 3rd parameter wants id3dshaderresourceview* const* . so cannot make way (because getting lvalue error): // std::unique_ptr<texture> mtexture; // id3d11shaderresourceview* texture::gettexture() const { // return mtexture; // } devicecontext->pssetshaderresources( 0u, 1u, &mtexture->gettexture() ); that's why found way around make way: auto tex = mtexture->gettexture(); devicecontext->pssetshaderresources( 0u, 1u, &tex ); however, i'd rid of auto tex = ... line. is there possibility change gettexture() method (or without changing it) write in first case? okay, have solved changing gettexture() method to: id3d11shaderresourceview* const* texture::gettexture() const { return &mtexture.p; // ccomptr<id3dshaderresourceview> mtexture; }
