clock_getres_time32

Intro

clock_getres_time32 - retrieves the resolution of the specified clock.

Description

clock_getres_time32 retrives the resolution of the specified clock in struct old_timespec32 variable provided in the tp argument. This function allows information about the resolution of the clock to be queried, for use in accurately measuring time intervals.

clock_getres_time32 exists for backward compatibility with 32bit systems, in replacement to clock_getres which takes timespec structure as an argument.

Arguments

  • which_clock:clockid_t[K] - clock id use to query its resolution. Supported clocks are the same as with clock_gettime.
  • tp:struct old_timespec32*[KU] - pointer to a buffer where the resolution of the clock will be stored.

Available Tags

  • K - Originated from kernel-space.
  • U - Originated from user space (for example, pointer to user space memory used to get it)

Hooks

sys_clock_getres_time32

Type

Kprobe

Purpose

To monitor and trace the execution of clock_getres_time32 syscall.

Example Use Case

clock_getres_time32 can be useful in various timing-related projects. For example, it can be used to compare the resolution of different clocks, or query a clock's resolution before a precise time measurement is taken with clock_gettime.

Issues

None.

  • clock_gettime - query the current time
  • clock_getres - query the resolution of a clock (64bit version)
