Hello,
How to execute a call back function after aio_write() or aio_read() in Sun Solaris 5.7?
I have filled the control block struct aiocb as follows:
aio_sigevent.sigev_signo = SIGEV
aio_sigevent.sigev_notify = SIGEV_THREAD
Then I have filled the call back function in ... (0 Replies)
Actually I got a list of file end with *.txt
I want to use the same command apply to all the *.txt
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.
For example:
I got the file below:
file1.txt
file2.txt

Hi All,
I am using splice function in for loop to delete particular element from array with one condition.
my $cnt=0;
foreach my $elem (@result)
{
if (condition){
splice(@result, $cnt, 1);}
else{
$cnt++;}
}
Now when in array, two elements comes sequentially with the... (3 Replies)
I need to detect the number of pages in a print job when it is available so I can warn users when they try to print a report much larger than they expected. Sometimes they are trying to print 1000 page reports when they thought they were getting a 10 page report.

Hello Unix experts,
If I could get any explanations on why the code below doesn't work it would be great !
My input looks like that ("|" delimited):

The goal is, if $2 is "ok", to remove everything before the pattern given in the match function... (5 Replies)

srand
rand(3C) Standard C Library Functions rand(3C)NAME
rand, srand, rand_r - simple random-number generator
SYNOPSIS
#include <stdlib.h>
int rand(void);
void srand(unsigned int seed);
int rand_r(unsigned int *seed);
DESCRIPTION
The rand() function uses a multiplicative congruential random-number generator with period 2**32 that returns successive pseudo-random num-
bers in the range of 0 to RAND_MAX (defined in <stdlib.h>).
The srand() function uses the argument seed as a seed for a new sequence of pseudo-random numbers to be returned by subsequent calls to
rand(). If srand() is then called with the same seed value, the sequence of pseudo-random numbers will be repeated. If rand() is called
before any calls to srand() have been made, the same sequence will be generated as when srand() is first called with a seed value of 1.
The rand_r() function has the same functionality as rand() except that a pointer to a seed seed must be supplied by the caller. If
rand_r() is called with the same initial value for the object pointed to by seed and that object is not modified between successive calls
to rand_r(), the same sequence as that produced by calls to rand() will be generated.
The rand() and srand() functions provide per-process pseudo-random streams shared by all threads. The same effect can be achieved if all
threads call rand_r() with a pointer to the same seed object. The rand_r() function allows a thread to generate a private pseudo-random
stream by having the seed object be private to the thread.
USAGE
The spectral properties of rand() are limited. The drand48(3C) function provides a better, more elaborate random-number generator.
When compiling multithreaded applications, the _REENTRANT flag must be defined on the compile line. This flag should be used only in mul-
tithreaded applications.
