System call vs POSIX call

Thu Aug 16 12:21:05 EDT 2018

Hi All,

I'm trying to get the difference between system call and POSIX call. System
calls are user mode API's (open(), close(), ioctl(),...) gets the kernel
service via software interrupt. What about POSIX calls and how it differs
with the system call.? Can anyone clarify me on this.
