The code above is what ive been working on but it prompts for a password no matter what even when i put it in the background. I dont know of anyway to get it to stop asking for a password

hi everyone. If you have a function created in your code and you want to find out how long it takes for it to run you can use a struct called gettimeofday().
so lets say we have a function like this
int myfunction (int r)
{
/*some math calculations*/
return answer;
}
How do i set up... (3 Replies)
Hello there, I just needed to know how to get the timing right when using the gcc __builtin_prefetch() function, that is, how many instructions before the actual utilization of the data should I make the prefetch call.

I was running some timings in my code to see which of several functions was the best and I've been getting some odd results. Here's the code I'm using:

clock_t start, end;
int n = 0, i = 0;
start = clock();

I have noticed the difference in byte swap timing between two Ubuntu systems. The bswap_32 used to work just fine on the old system, but on the new one it lags behind home-grown swap.

zegrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
