linux - unknown field 'ioctl' specified in initializer -


i implement simple example study usage of ioctl interface according book ldd3. when compiling codes, unknown field 'ioctl' specified in initializer. reported.

i guess difference of kernel version between ldd3's , mine causes error. i'm using debian 8 kernel 3.18.14, newer version 2.6 in ldd3.

i don't know how ioctl, or struct file_operations, changed form 2.6 3.18, please show me reading materials clarify it. of course, besides reading material, need 1 solution fix problem.

ioctl has been renamed unlocked_ioctl. e.g, see article: http://lwn.net/articles/115651/

other operations struct file_operations, mentioned in ldd3, haven't been changed.

go - Idiomatic way to handle template errors in golang -

say have html/template following: <html> <body> <p>{{somefunc .somedata}}</p> </body> and somefunc returns error. there idiomatic way deal this? if write directly responsewriter , status code 200 has been written before encounter error. var tmpl *template.template func handler(w http.responsewriter, r *http.request) { err := tmpl.execute(w, data) // "<html><body><p>" has been written... // err? } preferably return status code 400 or such, can't see way if use template.execute directly on responsewriter . there i'm missing? since template engine generates output on-the-fly, parts of template preceding somefunc call sent output. , if output not buffered, (along http 200 status) may sent. you can't that. what can perform check before call template.execute() . in trivial case should enough call somefunc() , check return value. if choose path , return value of somefunc() c...
