Hello!
I am working on a server where I should have 4 (resident)processes, one of them being "the father" of the others, so I do 3 forks. The problem that I have is that I do an accept (for sockets) in the "father" process and I want to transmit the job to one of the processes "child" with... (3 Replies)
Hi!
Can someone explain me exactly this technique? Why a process (PARENT) creates a copy of itself with FORK (CHILD)? What's the reason of this behaviour? Sorry, but I cannot understand the logic behind it.
Thanks. (4 Replies)
Hi,
I need to find/implement an application that FTPs (puts) all new files in a certain directory to an external storage unit. This application should check for new files every 10 seconds (leaving the FTP connection open in between the 10 seconds).
The easiest way would be if there are... (2 Replies)
Hello to UNIX Champs,
Can any body help me out to write the script using fork() thru shell scripting.....i am a layman to fork(), so please give me the link or any scripts which will help me out to know the details about fork. (1 Reply)
I need to ssh to a remote server and run my script there. This is my script.
$ssh = "ssh username@host";
$cmd = "$ssh 'cd <my dir> && < sudo Run_exe>'";
my $pid = fork;
if ($pid == 0){
exec $cmd;
}
When I run this I get:

Hello World!
I am writing code in C++ which have to launch another application X using exec().
I would like to set some limits on it using setrlimit etc...
My problem is that i don't know how to forbid using fork() and strlimit by application X.
How can i do it? (3 Replies)

punycode_decode - API function
SYNOPSIS
#include <punycode.h>
int punycode_decode(size_t input_length, const char [] input, size_t * output_length, punycode_uint [] output, unsigned char []
case_flags);
ARGUMENTS
size_t input_length
The number of ASCII code points in the input array.
const char [] input
An array of ASCII code points (0..7F).
size_t * output_length
The caller passes in the maximum number of code points that it can receive into the output array (which is also the maximum
number of flags that it can receive into the case_flags array, if case_flags is not a NULL pointer). On successful return it
will contain the number of code points actually output (which is also the number of flags actually output, if case_flags is not
a null pointer). The decoder will never need to output more code points than the number of ASCII code points in the input,
because of the way the encoding is defined. The number of code points output cannot exceed the maximum possible value of a
punycode_uint, even if the supplied output_length is greater than that.
punycode_uint [] output
An array of code points like the input argument of punycode_encode() (see above).
unsigned char [] case_flags
A NULL pointer (if the flags are not needed by the caller) or an array of boolean values parallel to the output array. Nonzero
(true, flagged) suggests that the corresponding Unicode character be forced to uppercase by the caller (if possible), and zero
(false, unflagged) suggests that it be forced to lowercase (if possible). ASCII code points (0..7F) are output already in the
proper case, but their flags will be set appropriately so that applying the flags would be harmless.
DESCRIPTION
Converts Punycode to a sequence of code points (presumed to be Unicode code points).
RETURN VALUE
The return value can be any of the Punycode_status values defined above. If not PUNYCODE_SUCCESS, then output_length, output, and
case_flags might contain garbage.
