zaccept()

#####int zaccept ( int sockfd, struct sockaddr * cliaddr, socklen_t * addrlen )

zaccept() call intercepts the accept system call.

zaccept() used with connection-based socket types (SOCK_STREAM, SOCK_SEQPACKET), It extracts the first connection request on the queue of pending connections for the listening socket, sockfd, creates a new connected socket, and returns a new file descriptor referring to that socket.

######Example usage:

#include "zerosocket.h"
⋮
int newclient_sock;
int server_sock;
struct sockaddr client_addr;
int addrlen;
//zsocket, zbind, and zlisten have been called
⋮
addrlen = sizeof(client_addr);
newclient_sock = zaccept((server_sock,&client_addr, &addrlen));

######Parameters:

Parameter	Description
sockd	sockfd is a socket that has been created with zsocket, bound to a local address with zbind, and is listening for connections after a zlisten
cliaddr	cliaddr is a pointer to a sockaddr structure. This structure is filled in with the address of the peer socket, as known to the communications layer
addrlen	addrlen argument is a value-result argument: the caller must initialize it to contain the size (in bytes) of the structure pointed to by addr; on return it will contain the actual size of the peer address

######Returns

On success, these system calls return a nonnegative integer that is a descriptor for the accepted socket. On error, -1 is returned, and errno is set appropriately.
