Welcome to the Linux Foundation Forum!
about fork()
i am learning the kernel,the fork() ,i have some questions,and read some from the net,but not very know about it
the source:
#include
#include
#include
void main()
{
int i;
int p_id;
printf("aaa");
p_id=fork();
if(p_id==0)
{
for(i=1;i<3;i++)<br />
{ printf("this is child process\n"); }
}
if(p_id==-1)
{
printf("fork new process error!\n");
}
if(p_id==0)
{
printf("iii");
for(i=1;i<3;i++)<br />
{ printf("this is parent process\n" ); }
}
printf("bbb");
}
[email protected]:~/lianxi/chapter2$ ./forktest
aaathis is child process
this is child process
iiithis is parent process
this is parent process
I know fork() copy the two same program to child,parent process,
why can show "aaa",cannot "bbb"

Cute! The code processor strips out the backslashes in the code example! Let's try doubling them to see if they display correctly...
Ok, that works. Note to forum moderator(s) - the code block processor is incorrectly stripping out new-line (backslash-n) in C code. Not good.
