I send you an attached file with the awk source of a simple function for rounding numbers in any scale. Of course there are some limits, but you can edit the code and make it better (if you can).
Have fun.
hello everybody!
I want to create a file with permissions for read, write, and execute to everybody using C, so I write this code:

Thus I try to find out the fastest way to write those same command in a script and then want to let them run automatics.

Hi,
from the manual
listen(2): listen for connections on socket - Linux man page
It has a parameter called backlog and it limits the maximum length of queue of pending list.
If I set backlog to 128, is it means no more than 128 packets can be handled by server?

H friends,
As we know, a function returns a value and that value is saved somwhere. like
int Sum( int x, int y )
{
return x + y;
}
Total = Sum( 10, 20 );
The value 30 is saved in variable Total.
Now the question is, what int value does the function main return, and where is it... (5 Replies)

fegetround
FEGETROUND(3) BSD Library Functions Manual FEGETROUND(3)NAME
fegetround, fesetround -- functions providing access to the floating-point rounding mode.
SYNOPSIS
#include <fenv.h>
#pragma STDC FENV_ACCESS ON
int
fegetround(void);
int
fesetround(int round);
DESCRIPTION
These functions provide control of floating-point rounding direction modes.
The fegetround() function gets the current rounding direction. It returns the value of the rounding direction macro representing the current
rounding direction, or a negative value if either there is no corresponding macro or if the rounding direction is not determinable.
The fesetround() function sets the rounding direction to be that specified by the argument round. If the argument is not equal to the value
of one of the rounding direction macros, the rounding direction is not changed. It returns zero if and only if the requested rounding direc-
tion was established.

feraiseexcept(3), feupdateenv(3)STANDARDS
These functions conform to ISO/IEC 9899:TC3.
