Hi Everyone!
How can we make a socket() system call from a linux module executing in kernel space?
If any one knows, kindly tell me. It will be great.
I want to use the socket interface in linux kernel space for sending raw packets over the network.

Greetings,
Please help me with the following :
Where can I find what means exactly and how to use each of the second
argument of the ioctl() system call in Linux/386 : FIOxxx (file IOCTL
requests), SIOxxx (socket IOCTL requests), TCxxx TIOxxx (terminal
IOCTL requests) ?

I encountered a variety of difficulties when implementing a system call as simple as HelloWorld example in Linux so far.
Firstly, according to the book "Linux Kernel Development Second Edition", I tried to implement a syscall in 2.6.31 but no way absolutely because 2.6.10 has a very different way... (5 Replies)

Hi, I'm writing a shell script where I want to call fork(). However I wrote like this "var=fork()" in c style and got this error:
"syntax error near unexpected token `(' "
How could I call fork() in shell script? Thanks in advance.

timerisset
TIMERADD(3) BSD Library Functions Manual TIMERADD(3)NAME
timeradd -- operations on time structure
SYNOPSIS
#include <sys/time.h>
void
timeradd(struct timeval *a, struct timeval *b, struct timeval *res);
void
timersub(struct timeval *a, struct timeval *b, struct timeval *res);
void
timerclear(struct timeval *tv);
int
timerisset(struct timeval *tv);
int
timercmp(struct timeval *a, struct timeval *b, CMP);
void
timespecadd(struct timespec *a, struct timespec *b, struct timespec *res);
void
timespecsub(struct timespec *a, struct timespec *b, struct timespec *res);
void
timespecclear(struct timespec *ts);
int
timespecisset(struct timespec *ts);
int
timespeccmp(struct timespec *a, struct timespec b, CMP);
DESCRIPTION
These macros are provided for manipulating the timeval and timespec structures described in timeval(3).
The timeradd() and timespecadd() macros add the time information stored in a to b, storing the result in res. With timeradd() the results
are simplified such that the value of res->tv_usec is always less than 1,000,000 (1 second). With timespecadd() the res->tv_nsec member of
struct timespec is always less than 1,000,000,000.
The timersub() and timespecsub() macros subtract the time information stored in b from a and store the resulting structure in res.
The timerclear() and timespecclear() macros initialize the structures to midnight (0 hour) January 1st, 1970 (the Epoch). In other words,
they set the members of the structure to zero.
The timerisset() and timespecisset() macros return true if the input structure is set to any time value other than the Epoch.
The timercmp() and timespeccmp() macros compare a to b using the comparison operator given in CMP. The result of the comparison is returned.
SEE ALSO timeval(3)HISTORY
The timeradd() family of macros first appeared in NetBSD 1.1. These were later ported to FreeBSD 2.2.6. The timespec() family of macros
first appeared in NetBSD 1.2.
