Manpages GETSOCKNAMESection: Linux Programmer's Manual (2)Updated: 1993-07-24 Index Return to Main Contents NAMEgetsockname - get socket nameSYNOPSIS#include <sys/socket.h>int getsockname(int s , struct sockaddr * name , socklen_t * namelen ) DESCRIPTIONGetsockname 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).RETURN VALUEOn success, zero is returned. On error, -1 is returned, and errno is set appropriately.ERRORS
CONFORMING TOSVr4, 4.4BSD (the getsockname function call appeared in 4.2BSD). SVr4 documents additional ENOMEM and ENOSR error codes.NOTEThe third argument of getsockname is in reality an `int *' (and this is what BSD 4.* and libc4 and libc5 have). Some POSIX confusion resulted in the present socklen_t. The draft standard has not been adopted yet, but glibc2 already follows it and also has socklen_t. See also accept(2).SEE ALSObind(2), socket(2)
