SYNOPSIS


.In sys/types.h
.In sys/socket.h int getpeername int s struct sockaddr * restrict name socklen_t * restrict namelen

DESCRIPTION

The getpeername system call returns the name of the peer connected to socket s. 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). The name is truncated if the buffer provided is too small.

[ENOTCONN]

[ENOBUFS]
