 Name

    bindresvport - bind a socket to a privileged IP port

    #include<netinet/in.h>

    bindresvport(sd,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.
