- assign a local protocol address to a socket
#include <sys/socket.h> int
bind (int s const struct sockaddr *addr socklen_t addrlen);
assigns the local protocol address to a socket.
When a socket is created
it exists in an address family space but has no protocol address assigned.
system call requests that
be assigned to the socket.
Binding an address in the UNIX domain creates a socket in the file
system that must be deleted by the caller when it is no longer
The rules used in address binding vary between communication domains.
Consult the manual entries in section 4 for detailed information.
For maximum portability, you should always zero the socket address structure
before populating it and passing it to
Rv -std bind
system call will fail if:
Bq Er EAGAIN
Kernel resources to complete the request are
Bq Er EBADF
is not a valid descriptor.
Bq Er ENOTSOCK
is not a socket.
Bq Er EADDRNOTAVAIL
The specified address is not available from the local machine.
Bq Er EADDRINUSE
The specified address is already in use.
Bq Er EACCES
The requested address is protected, and the current user
has inadequate permission to access it.
Bq Er EFAULT
argument is not in a valid part of the user
The following errors are specific to binding addresses in the UNIX domain.
Bq Er ENOTDIR
A component of the path prefix is not a directory.
Bq Er ENAMETOOLONG
A component of a pathname exceeded 255 characters,
or an entire path name exceeded 1023 characters.
Bq Er ENOENT
A prefix component of the path name does not exist.
Bq Er ELOOP
Too many symbolic links were encountered in translating the pathname.
Bq Er EIO
An I/O error occurred while making the directory entry or allocating the inode.
