|Subject: [PATCH] Apply quickcancel
|
|Cancel slock by moving the mouse within a certain time-period after
|slock started. The time-period can be defined in seconds with the
|setting *timetocancel* in the config.h. This is useful if you forgot to
|disable `xautolock` during an activity that requires no input (e.g.
|reading text, watching video).
|
|Changes from the 1.4 version: use CLOCK_MONOTONIC instead of time(NULL)
|to prevent bypassing the lock by setting the system clock back.
