bindresvport - bind a socket to a privileged IP portSYNOPSIS
#include <sys/types.h> #include <netinet/in.h> int bindresvport(sd, sin) int sd; struct sockaddr_in *sin;
DESCRIPTION
bindresvport() is used to bind a socket descriptor to a privileged IP port, that is, a port number in the range 0-1023. The routine returns 0 if it is successful, otherwise -1 is returned and errno set to reflect the cause of the error.
Only root can bind to a privileged port; this call will fail for any other users.
