Deleting file after progeam execution in batch -


i having simple question, having simple batch script: 

for /l %%x in (1, 1, 3) start /wait c:\some.exe -verbose c:\somelog.txt del c:\somelog.txt

after each execution file creates log, , want remove log before next loop execution, execution works fine when add del command having problems, looks log being deleted early.

is there possible way delay del command ??

when running multiple command nest them readability. 

for /l %%x in (1, 1, 3) (     start /wait c:\some.exe -verbose c:\somelog.txt      del c:\somelog.txt  )

you way well

for /l %%x in (1, 1, 3) (start /wait c:\some.exe -verbose c:\somelog.txt &del c:\somelog.txt)

but not mean executable respecting wait option. many programs not. use exe directly without using start @ all.

c++ - CPP, 'X' button listener -

i'm writing cpp program, , want execute function when 'x'(shut down) button pressed. for example, have infinite loop prints same thing everytime iterates, until 'x' button pressed, , want execute function before process ends. is there kind of listener matter? or other solution maybe (like delaying process shut down few seconds or something)? thanks! if want execute before process ends, can register std::atexit handler. function called before process exits.

r - Add string of (variable number of) arguments to a function within a function -

let's have function creates x number of objects based on length of input variable. want x number of objects used arguments in function supply function. assumign number of arguments variable (based on number of argument names provided), how can this? can via string of argument names perhaps? a non-working example illustrate i'm asking: (in case, using arguments created outside function simplify example): foo <- 1:5 na.rm <- t func <- mean f1 <- function(func,arg.names) { func(get(arg.names)) } f1(func,arg.names = c('foo','na.rm') how do in way get 's arguments list? we can try mget f1 <- function(func,arg.names) { lst <- mget(arg.names, envir = parent.frame()) func(lst[[1]], na.rm = lst[[2]]) } f1(func, arg.names = c('foo', 'na.rm')) #[1] 3 or option do.call (as mentioned in @thelatemail's post) change name of first list element 'x' x 'data' argument ...
