facing problem in binding

jsulm

@ManiRon Why don't you use http://doc.qt.io/qt-5/qtnetwork-index.html ? Then your question would be related to Qt.
And you don't even mention what problem you face...

ManiRon

@jsulm my problem is when i try to bind data it returns an error saying the bind failed: invalid argument

jsulm

@ManiRon Are you aware that your question is completely unrelated to Qt?
You're using low level socket API not Qt.
Please post at least the whole compiler error.

ManiRon

@jsulm yes sir this is what the error say invalid argument in bind

jsulm

@ManiRon Please copy paste the compiler error

@ManiRon So, it's not a compiler error but a runtime error.
You should zero your address first like

bzero((char *) &address, sizeof(address));

As shown here http://www.cs.rpi.edu/~moorthy/Courses/os98/Pgms/socket.html

@jsulm said in facing problem in binding:

bzero((char *) &address, sizeof(address));

I used memset(&address, 0, sizeof(sockaddr_in)); this and set it to zero but still the problem exists

jsulm

@ManiRon Are you sure you want to use SOCK_DGRAM (UDP) and not SOCK_STREAM (TCP)?
If I remember correctly you don't need bind() for UDP.

ManiRon

@jsulm

I have to check

@jsulm

actually socket creation itself is a problem
server_fd = socket(AF_INET, SOCK_DGRAM, IPPROTO_IP)

here server_fd is -1
