mtcp_getsockname − get socket name
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.
The argument sockfd is not a valid socket descriptor.
addrlen argument is invalid (e.g., is negative).
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.
