pipes with gtk

[guigtk <guigtk ole com>]

Below there is a pice of code to work with a backgound binary process 
(in this case a ftp).

I want to send commands from a Gtk text entry and receive a the 
response into a text box. In this example I write with accion and I 
want to read the the response with in a text box.

When I try read the data with  while (fgets(str,BUFSIZE, fout) != 
NULL), I cant get out from the loop ???

What do i have to use to read str and continue???

Thanks a million

Guillermo


SOURCE CODE:

#include <stdio.h>
#include <unistd.h>
#include <string.h>
#include <sys/types.h>

#define BUFSIZE 1024


        pid_t childpid;
        char str[BUFSIZE];
        int pin[2],pout[2],len;
        FILE *fout;
        
        


void accion(char *instruccion){                
                sprintf(str,"%s\n", instruccion);
                printf("%s",str);
                len=strlen(str);
                write(pin[1],str,len);
                fout=fdopen(pout[0],"r");
          
            // to send to text box
            while (fgets(str,BUFSIZE, fout) != NULL) printf("#%s", 
str);// This is the problem

                     }                     
                system("sleep 1"); // just to no get broken pipe ???
}


        
int main(){
        
        pipe(pin);
        pipe(pout);
        
        childpid=fork();
        if(childpid<0){
                       perror("fork");
                       return -2;
        }
        
        if(childpid==0){
                close(pin[1]);
                close(pout[0]);
                dup2(pin[0],0);
                dup2(pout[1],1);
                execlp("ftp","ftp","-n","192.168.1.106",NULL);
        }
        else{
                close(pin[0]);
                close(pout[1]); 
                sprintf(str,"user anonymous \"pepe pepe es\"\n");
                printf("%s",str);
                len=strlen(str);
                write(pin[1],str,len);
                fout=fdopen(pout[0],"r");
                
            }
                //while (fgets(str,BUFSIZE, fout) != NULL) printf("%s", 
str);
                
        
        

accion("ls");           // to send from a text entry
printf("ls\n");         // to send from a text entry
accion("cd pub");               // to send from a text entry
accion("get file.bmp"); // to send from a text entry
accion("quit");         // to send from a text entry

        return 0;
}
