mtcp_getsockname - get socket name #include <mtcp_api.h> "int mtcp_getsockname(mctx_t " mctx ", int " sockfd ", struct sockaddr *" addr ", socklen_t *" addrlen ); mtcp_getsockname () returns the current address to which the socket "sockfd" is bound, in the buffer pointed to by "addr." The "addrlen" argument should be initialized to indicate the amount of space (in bytes) pointed to by "addr." On return it contains the actual size of the socket address. An mtcp_getsockname () call takes an additional argument named "mctx" that represents the per-core mTCP context in an application (see mtcp_create_context() for details).

Returns zero on success; -1 on failure. In case of failure, "errno" is set appropriately. """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

10 "EBADF" The argument "sockfd" is not a valid socket descriptor.

10 "EINVAL" "addrlen" argument is invalid (e.g., is negative).

10 "ENOTSOCK" The argument "sockfd" is pointing to an invalid mTCP socket. """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

The third argument of mtcp_getsockname() is in reality an "int *" (and this is what 4.x BSD and libc4 and libc5 have). Some POSIX confusion resulted in the present "socklen_t", also used by glibc. """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
