Re: [Dev-C++] Sleep / for specified time delay :( ?

[Robert A. <ral...@gm...>]

Please for the sake of yourself and the sanity of anyone who later may
need to debug or modify your code.
Please keep it simple and flexible by following two rules.

1) Create a customer Function, for example customerSleep(X) where X is
clock ticks, nano seconds, seconds, minutes, etc... what ever you
need.
2a) Check the major standards for something that does what you need
and use that if at all possible in side your customer function.
2b)I would suggest posix standard, sleep if you don't need a precise
delay, otherwise use the timeout feature of poll system call.
3c)If for some reason neither of those work, use  something for your OS.

Following rule 1 will mean that you only need to make adjustments in
one place if you need to fix/change or port the delay to another
platform, or version, etc...

Following the second rule will mean that it's more likely you won't
need to make a fixes/changes for bugs or ports.

Hope this helps,
Robert
