GETSOCKNAME(2)						      BSD System Calls Manual						    GETSOCKNAME(2)

NAME

     getsockname -- get socket name

SYNOPSIS

     #include <sys/socket.h>

     int
     getsockname(int s, struct sockaddr *name, int *namelen);

DESCRIPTION

     Getsockname() returns the current name for the specified socket.  The namelen parameter should be initialized to indicate the amount of space
     pointed to by name.  On return it contains the actual size of the name returned (in bytes).

DIAGNOSTICS

     A 0 is returned if the call succeeds, -1 if it fails.

ERRORS

     The call succeeds unless:

     [EBADF]		The argument s is not a valid descriptor.

     [ENOTSOCK] 	The argument s is a file, not a socket.

     [ENOBUFS]		Insufficient resources were available in the system to perform the operation.

     [EFAULT]		The name parameter points to memory not in a valid part of the process address space.

SEE ALSO

     bind(2), socket(2)

BUGS

     Names bound to sockets in the UNIX domain are inaccessible; getsockname returns a zero length name.

HISTORY

     The getsockname() function call appeared in 4.2BSD.

SYNOPSIS

     #include <sys/types.h>

     int
     getsockname(int s, struct sockaddr * restrict name, socklen_t * restrict namelen);

DESCRIPTION

     The getsockname() system call returns the current name for the specified socket.  The namelen argument should be initialized to indicate the
     amount of space pointed to by name.  On return it contains the actual size of the name returned (in bytes).

RETURN VALUES

     The getsockname() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to
     indicate the error.

ERRORS

     The call succeeds unless:

     [EBADF]		The argument s is not a valid descriptor.

     [ECONNRESET]	The connection has been reset by the peer.

     [EINVAL]		The value of the namelen argument is not valid.

     [ENOTSOCK] 	The argument s is a file, not a socket.

     [ENOBUFS]		Insufficient resources were available in the system to perform the operation.

     [EFAULT]		The name argument points to memory not in a valid part of the process address space.
