bindresvport()

Bind a socket to a privileged IP port

Synopsis:

#include <sys/types.h>
#include <netinet/in.h>

int bindresvport( int sd,
                  struct sockaddr_in * sin );

Since:

BlackBerry 10.0.0

Arguments:

sd: The socket descriptor to bind to the port.
sin: A pointer to a sockaddr_in structure that specifies the privileged IP port.

Library:

libsocket

Use the -l socket option to qcc to link against this library.

Description:

The bindresvport() function binds a socket descriptor to a privileged IP port (i.e. a port number in the range 0-1023).

Only root can bind to a privileged port; this call fails for any other user.

Returns:

0: Success.
-1: An error occurred ( errno is set).

Errors:

EACCES: You must be root to call bindresvport().
EADDRINUSE: The specified address is already in use.
EADDRNOTAVAIL: The specified address isn't available from the local machine.
EBADF: Invalid descriptor sd.
EFAULT: The sin parameter isn't a valid pointer to a sockaddr_in structure.
EINVAL: The socket is already bound to a port.
EPFNOSUPPORT: The protocol family isn't supported.
