OSTimeTickHook

void OSTimeTickHook( void );

Description

This function, as included with Dynamic C, is a stub that does nothing except return. It is called every clock tick. Code in this function should be kept to a minimum as it will directly affect interrupt latency. This function must preserve any registers it uses other than the ones that are preserved at the beginning of the periodic interrupt (periodic_isr in VDRIVER.LIB), and therefore should be written in assembly. At the time of this writing, the registers saved by periodic_isr are: AF,IP,HL,DE and IX.

Library
