ITIMER_VIRTUAL

[andrew browning]

Does anyone know how to make ITIMER_VIRTUAL display the elapsed time as
a possitive floating point number? when i:

printf("%ld")

i get a signed long int

and when i:

printf("%f")

i get 0.00000000

any help is appreciated

Hi,

I don't know how you define ITIMER_VIRTUAL (it is not in standard C++
anyway) but how about the following?

std::cout<<static_cast<float>(ITIMER_VIRTUAL)

What is type ITIMER_VIRTUAL? It is non-standard (which could indicate
you should be asking this in a platform-specific newsgroup; cf.
http://www.parashift.com/c++-faq-lit....html#faq-5.9). If you
use iostreams instead of printf (see
http://www.parashift.com/c++-faq-lit...html#faq-15.1), you
don't have to worry about what type it is.

Try this if you using linux (otherwise search the web) :
man setitimer
