I am new to using djgpp under dos, being a unix programmer.  I am having
trouble with delays.

Can I rely on usleep to give me accurate timings.

Giving usleep a value of 10000-12500 produces the same delay, whereas 13000
gives the same as 20000, where I am going wrong.


I would like to put a delay into a loop of about 1/100 sec. how is the best
way to acheive this

I am also looking to work with microprocessors where I will need accurate
timings of nanoseconds, how can this be best acheived.

TIA

Simon
