What do I do wrong?

I had to create a shared memory segment which allows the creation of 8 child processes each with 1024 bytes and contains a common buffer area of 2096bytes.
i was able to create the shared memory with shm_open() followed by ftruncate() and mmap() system calls.
but for the shared buffer, i... (3 Replies)
Hi,
Would any one be so kind to explain me :

Specialy what is the impact of :

and
virtual memory
on performance of applications for a user.
Many thanks.

pthread_detach
pthread_detach(3) Library Functions Manual pthread_detach(3)NAME
pthread_detach - Marks a thread object for deletion.
LIBRARY
DECthreads POSIX 1003.1c Library (libpthread.so)
SYNOPSIS
#include <pthread.h>
int pthread_detach(
pthread_t thread);
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
IEEE Std 1003.1c-1995, POSIX System Application Program Interface
PARAMETERS
Thread object being marked for deletion.
DESCRIPTION
This routine marks the specified thread object to indicate that storage for the corresponding thread can be reclaimed when the thread ter-
minates. This includes storage for the thread argument's return value, as well as the thread object. If thread has not terminated when
this routine is called, this routine does not cause it to terminate.
When a thread object is no longer referenced, call this routine.
The results of this routine are unpredictable if the value of thread refers to a thread object that does not exist.
A thread can be created already detached by setting its thread object's detachstate attribute.
The pthread_join(3) routine also detaches the target thread after pthread_join(3) returns successfully.
RETURN VALUES
If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows:
Successful completion. The value specified by thread does not refer to a joinable thread. The value specified by thread cannot be found.
ERRORS
None
