Need some assistance involving a forking in C - c

Question

Hello so I've been working on this for quite awhile now and cannot figure it out.
I'm trying to set up a connection to a client using a specific port number. For some reason the child process is exiting if my While loop is included in the code. When I take the while loop out everything executes as intended. Any guidance?
Here's my code
> #include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
int main(int argc, char *argv[]){
if (argc < 2) {
printf("Please enter a port");
} else {
printf("test2");
int socketfd;
pid_t pid, sid;
//Fork
pid = fork();
if (pid < 0) {
perror("Fork failed");
exit(1);
}
if (pid > 0) {
printf("exiting");
exit(0);
}
if (pid == 0) {
printf("Hi");
sid = setsid();
if (sid < 0){
printf("failure");
}
//Start the Daemon
printf("Test");
socketfd = socket(AF_INET, SOCK_STREAM, 0);
if(socketfd < 0){
printf("socket error");
}
int portNumber = atoi(argv[1]); //Port number entered in by user.
struct sockaddr_in server;
struct sockaddr_in clientAddress;
bzero((char *) &server, sizeof(server)); // Clear buffer for server address
server.sin_addr.s_addr = INADDR_ANY;
server.sin_port = htons(portNumber);
server.sin_family = AF_INET;
socklen_t clientLength;
printf("Test3");
if (bind(socketfd, (struct sockaddr *) &server, sizeof(server)) == -1)
{
perror("bind call failed");
}
printf("Test5");
listen(socketfd, 5);
clientLength = sizeof(clientAddress);
printf("Test6");
while(1) {
int client_socketfd;
int x;
client_socketfd = accept(socketfd, (struct sockaddr *) &clientAddress, &clientLength);
if(client_socketfd == -1){
perror("ERROR: \n");
}
FILE * pFile;
char receivedFile[1000];
char rawData[1000];
bzero(receivedFile, 1000);
if (read(client_socketfd,receivedFile,1000) == -1){
perror("Read Failure");
}
printf("Received File %s",receivedFile);
pFile = fopen(receivedFile, "r");
if(pFile == NULL){
perror("Cannot open file");
}
if(fgets(rawData,1000,pFile) != NULL) {
int fileLength = strlen(rawData);
for(x = 0; x < fileLength; x++){
printf("%s\n",rawData[x]);
}
} else {
perror("Nothing in the file!\n");
}
}
}
}
return 0;
}
Here's what happens when I compile and run the above code:
Here's the test I did to source the issue to the while loop.
> #include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
int main(int argc, char *argv[]){
if (argc < 2) {
printf("Please enter a port");
} else {
printf("test2");
int socketfd;
pid_t pid, sid;
//Fork
pid = fork();
if (pid < 0) {
perror("Fork failed");
exit(1);
}
if (pid > 0) {
printf("exiting");
exit(0);
}
if (pid == 0) {
printf("Hi");
sid = setsid();
if (sid < 0){
printf("failure");
}
//Start the Daemon
printf("Test");
socketfd = socket(AF_INET, SOCK_STREAM, 0);
if(socketfd < 0){
printf("socket error");
}
int portNumber = atoi(argv[1]); //Port number entered in by user.
struct sockaddr_in server;
struct sockaddr_in clientAddress;
bzero((char *) &server, sizeof(server)); // Clear buffer for server address
server.sin_addr.s_addr = INADDR_ANY;
server.sin_port = htons(portNumber);
server.sin_family = AF_INET;
socklen_t clientLength;
printf("Test3");
if (bind(socketfd, (struct sockaddr *) &server, sizeof(server)) == -1)
{
perror("bind call failed");
}
printf("Test5");
listen(socketfd, 5);
clientLength = sizeof(clientAddress);
printf("Test6");
}
}
return 0;
}
This code successfully enters the child and prints out all the "Tests"
