tic compiler
tic – the terminfo entry-description compiler
The command tic translates a terminfo file from source format into compiled format. The compiled format is necessary for use with the library routines in ncurses(3NCURSES).

__fpending programming
The __fpending() function returns the number of bytes in the output buffer. For wide-oriented streams the unit is wide characters. This function is undefined on buffers in reading mode, or opened read-only.
On POSIX-compliant platforms, SIGSEGV is the signal sent to a process when it makes an invalid memory reference, or segmentation fault.
#include<stdio.h>
#include<stdio_ext.h>
main()
{
size_t love;
FILE *ptr;
ptr=fopen("home/jeffrin/tester", "w");
love= __fpending(ptr);
printf("\n %p \n",love);
}
(gdb) r

SMBus controller
SMBus is the System Management Bus defined by Intel in 1995. It is used in personal computers and servers for low-speed system management communications. An SMBus controller is integrated into most Intel® chipsets.
The SMBus Controller (or system bus controller) is part of the Intel chipset. It monitors your system board’s temperature and voltage. Programs that read your hardware sensors need the controller.

Bus
An electronic pathway. In networks, a configuration (topology) with a single linear cable, terminated at each end, to which computers and devices are connected. There are no loops or branches in the cable. Also called a daisy chain.
Topology.
The arrangement in which the nodes of a LAN are connected to each other.
