0xfeeefeee is a Magic Number[^] which has a meaning. This essentially means that you are trying to access memory AFTER it has been freed. You should begin debugging by checking the variables that you are accessing in your worker thread.

Anyone can tell me How to remove segmentation fault from these program
#include<stdio.h>
#include<unistd.h>
#include<string.h>
int main()
{
char *buf;
int nread;
nread=read(0,&buf,strlen(buf)); // in these statement i am getting segmentation fault
printf("buffer size is %d\n",nread);
if(nread == -1)
{
write(2,"An error occured in read function\n",27);
}
else
{
if(nread==0)
write(2,"Data is not written to the filedescriptor\n",27);
else
write(2,"Everything went smoothly it has read the bytes\n",27);
}
}
output
sandeep@sandeep $ ./a.out <x
buffer size is 62
Everything went smoothly itSegmentation fault

Try:
#include<stdio.h>
#include<unistd.h>
#include<string.h>
int main()
{
char buf[128];
int nread;
nread = read(0, buf, sizeof(buf));
printf("buffer size is %d\n", nread);
...
}

Are you unable to see the difference between char *buf and char buf[128]?

You should allocate memory for you buffer and call correctly the function.
For instance:
char buf[0x100];
int nread;
nread = _read( stdin, buf, sizeof(buf));

thanks
the above may work with memset()
thank you

You don't need memset, you must allocate memory for the buffer (you didn't), either onto the stack (as I did) or in the heap via, for instance, malloc.

Your buf variable is an uninitialized pointer, it will surely segfault when you pass it to strlen. I also suspect that read won't work the way you think it will work, but that's just a guess right now...
