problems with select ( ) function

[Sonbol]

Hi,

I am new to linux programming. I am using c to develop a program that aims to create many children in order to communicate with their parents through pipes

I need the parent to wait for all the children to finish processing and write to their parent using the appropriate pipe for each children. I know that I may use the select function for this purpose and I have read a lot about it but I don't know how to use it in my program

code skeleton can be like this

int main(int argc,char *argv[])
{

fd_set rfds;
int i;
int fd[2];
FD_ZERO(&rfds);

for(i=0;i<atoi(argv[1]);i++)
{

pipe(fd);
if(!fork())
//child process and write to the parent then exit
else
//i want the select function to be here

}
return 0;

}
