Are programs like sys_open( ) ,sys_read( ) et al examples of system level programs ?
Are the programs written on schedulers ,thread library , process management, memory management, et al called systems programs ? How are they different from the programs that implement functions like open() , printf() , scanf() , read() .. they have a prefix sys_open, sys_close, sys_read etc , right ? Is there any difference of hierarchy between the programs that implement system calls and system level programs like that implement thread library, process management , memory managemnt etc..
Hope you understood my qstn
