similar question...also gives segmentation fault...plz explain...
http://ideone.com/nlpzT
#includeunistd.h#includefcntl.h#includestdio.h
int main()
{
int pid;
printf
http://www.opengroup.org/onlinepubs/009695399/functions/printf.html(Parent\n);
pid = vfork();
Both share the same address space that includes even the stack
The child *returns first clearing the stack.*Now when the parent process
tries to return the child process had already cleared the stack.SO it no
longer belongs to the parent process,so sigsegv.
Try with gdb dissassemble and
thnx saurabh.u rock :)

hi it gives that
in fun1:incompatible implicit declaration of built-in function ‘printf’
in fun2:incompatible implicit declaration of built-in function ‘printf’

Read this documentation
http://pubs.opengroup.org/onlinepubs/7908799/xsh/vfork.html
vfork creates read-only copy of the parent. You cannot call function or
assign value to variable except pid_t. Use fork and it should succeed.
PS: Please ask questions related to Algorithms, as it is algorithm
#includesys/types.h
int fun1()
{
if(vfork()==0);
else printf(Fun1\n);
}
int fun2()
{
printf(Fun2\n);
}
int main()
{
fun1();
fun2();
return 0;
}
Why does this program giving seg fault.?

this is ma code for http://www.spoj.pl/problems/ANARC08H/musical
chairs
i m using dynamic programming
for input lik

i m getting seg. fault
plz tell hw to modify my program
#includeiostream
#includecstdio
using namespace std;
long long arr[10003][10003];

using array is mecessary as constraints are n,d100
so recursion cannot go to that much depth as we have stack limits
what do u suggest
