bind failed: Cannot assign requested address - c

Question

I'm trying to write a C program that listens on a port on my machine.
I'm running into a strange error.
Whenever I try to bind the socket to a fixed ip (either 127.0.0.1 or my actual IP) I get a "bind failed: Cannot assign requested address" error.
However when I pass INADDR_ANY to the bind as the address to bind to, it works.
These are the only two IPs I have so it can't be that the 0.0.0.0 works because of some other IP address I have available.
Here is the code:
#include<sys/types.h>
#include<stdio.h>
#include<sys/socket.h>
#include<netinet/in.h>
#include<errno.h>
#include<stdlib.h>
#include<string.h>
int main()
{
int port = 1234; /* port number */
int rqst; /* socket accepting the request */
socklen_t alen; /* length of address structure */
struct sockaddr_in my_addr; /* address of this service */
struct sockaddr_in client_addr; /* client's address */
int sockoptval = 1;
int svc;
/* create a TCP/IP socket */
if ((svc = socket(AF_INET, SOCK_STREAM, 0)) < 0) {
perror("cannot create socket");
exit(1);
}
/* allow immediate reuse of the port */
setsockopt(svc, SOL_SOCKET, SO_REUSEADDR, &sockoptval, sizeof(int));
/* bind the socket to our source address */
memset((char*)&my_addr, 0, sizeof(my_addr)); /* 0 out the structure */
my_addr.sin_family = AF_INET; /* address family */
my_addr.sin_port = htons(port);
//my_addr.sin_addr.s_addr = htonl(INADDR_ANY); /* Works! */
my_addr.sin_addr.s_addr = htonl(inet_addr("127.0.0.1")); /* Fails! */
if (bind(svc, (struct sockaddr *)&my_addr, sizeof(my_addr)) < 0) {
perror("bind failed");
exit(1);
}
printf("Listening on %d\n", my_addr.sin_addr.s_addr);
/* set the socket for listening (queue backlog of 5) */
if (listen(svc, 5) < 0) {
perror("listen failed");
exit(1);
}
/* loop, accepting connection requests */
for (;;) {
while ((rqst = accept(svc, (struct sockaddr *)&client_addr, &alen)) < 0) {
/* we may break out of accept if the system call */
/* was interrupted. In this case, loop back and */
/* try again */
if ((errno != ECHILD) && (errno != ERESTART) && (errno != EINTR)) {
perror("accept failed");
exit(1);
}
}
/* the socket for this accepted connection is rqst */
}
}

The function inet_addr returns the address already in network order:
The inet_addr() function converts the Internet host address cp from
IPv4 numbers-and-dots notation into binary data in network byte order
So drop the htonl.
