drv_usectohz
drv_usectohz(9F) Kernel Functions for Drivers drv_usectohz(9F) NAME
drv_usectohz - convert microseconds to clock ticks SYNOPSIS
#include <sys/types.h> #include <sys/ddi.h> clock_t drv_usectohz(clock_t microsecs); INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI). PARAMETERS
microsecs The number of microseconds to convert. DESCRIPTION
drv_usectohz() converts a length of time expressed in microseconds to a number of system clock ticks. The time arguments to timeout(9F) and delay(9F) are expressed in clock ticks. drv_usectohz() is a portable interface for drivers to make calls to timeout(9F) and delay(9F) and remain binary compatible should the driver object file be used on a system with a different clock speed (a different number of ticks in a second). RETURN VALUES
The value returned is the number of system clock ticks equivalent to the microsecs argument. No error value is returned. If the clock tick equivalent to microsecs is too large to be represented as a clock_t, then the maximum clock_t value will be returned. CONTEXT
drv_usectohz() can be called from user or interrupt context. SEE ALSO
