c++ - C++11: struct timeval -

-

i told not include c headers <stdio.h> in c++ program, use <cstdio> etc. instead. how struct timeval without including <sys/time.h>?

alternative question, there c++11 alternative using select/poll (on posix system)?

the <cstdio> , similar c++ variants c standard library. <sys/time.h> not part of c standard library @ (it part of posix interface certan os's), there no such thing c++ specific sys/ctime, no, have use same header-file in c.

the main reason having c style , c++ style header apply extern "c" functions declared in headerfile. in systems, may required wrap function this:

 extern "c" {  #include <sys/time.h>  }

but in linux system, in standard <sys/time.h> file.

is using ( condition or condition b , condition c ) the same as ( condition , condition c) or (condition b , condition c) no. first condition is: (condition a) or (condition b , condition c) and second is: (condition , condition c) or (condition b , condition c) you can see difference between them.

c++ - NetBeans Remote Development with additional configuration -

-
i'm trying use netbeans (7.3.1) work on remote project. my configuration following: my local machine windows 7 laptop. doesn't have tools. in particular neither compiler nor debugger. have netbeans ide , putty example. source code, make scripts , (eventually) build results located on remote storage shared across servers , "locals". (i might switch single server storage faster don't think matters @ all.) i'm accessing using sshfs manager . sshfs manager takes server name, path on server, user name , ssh private key. in result mounts directory on server disk on windows. works fine. (although directories, possibly links, represented files in windows explorer, don't know if matters...) netbeans project located on local machine don't think matters , place remotely well. prefer keep "off source" don't have add ignores version control. in netbeans did procedure described in remote developement tutorial . seems successful. netbeans c...
