Dear Corona688,

I want to use key of Scroll Lk to lock the current screen.
I'm quite new in linux c development. But familiar with windows c, c++ programming.

The context is like this:
I want to migrate the application program of Turbo C in Dos OS to Linux environment.
I think you may be expert in Turbo C program.
One function is to get the status of current screen.(locked or unlocked) and set the current screen to be locked or unlocked.

I don't know how to design this kind of migration. Maybe I should not translate line by line, but use another more sensible method.
Can you give some suggestions on this? Thank you very much!

MEMORY_PRESSURE(1)					    BSD General Commands Manual 					MEMORY_PRESSURE(1)

NAME

     memory_pressure -- Tool to apply real or simulate memory pressure on the system.

SYNOPSIS

     memory_pressure [-l level] | [-p percent_free] | [-S -l level]

OPTIONS

     -l <level> Apply real or simulate memory pressure (if specified alongside simulate argument) on the system till low memory notifications cor-
     responding to <level> are generated. Supported values are "warn" and "critical".

     -p <percent_free> Allocate memory till the available memory in the system is <percent_free> of total memory. If the percentage of available
     memory to total memory on the system drops, the tool will free memory till either the desired percentage is achieved or it runs out of memory
     to free.

     -S Simulate memory pressure on the system by placing it artificially for <sleep_seconds> duration at the "warn" or "critical" level.

     -s <sleep_seconds> Duration to wait before allocating or freeing memory if applying real pressure. In case of simulating memory pressure,
     this is the duration the system will be maintained at an artifical memory level.

DESCRIPTION

     A tool to apply real or simulate memory pressure on the system
