I am working on sxitwi.c and have a question on the tsleep function. Any documentation describes the timo parameter to tsleep as:
If non-zero, the process will sleep for at most timo/hz seconds. If this amount of time elapses and no wakeup(ident) has occurred, and no signal (if PCATCHwas set) was posted, tsleep() will return EWOULDBLOCK. I would like to know what timo/hz means. Hz is the symbol for cycles, but what does it mean in this context? If the timo parameter is set to 100, does tsleep sleep for at most 100 seconds or 100 divided by something?
