How can I convert an IP address to a char string?

I need to convert an IP address to a char string (xxx.xxx.xxx.xxx) so that I can send it to an html page using "writesafestring". I don't see that "Showip" can be made to work for this situation.
Thanks,
Ron Neal

There are probably many ways. Here is one use the old C sprintf (instead of iostreams which are currently causing me a problem). This came from my namespace NNbSysUtils so you will need to strip that off and put the method wherever you deem suitable.
Code: Select all
//===========================================================================
// IpToAscii()
// Convert an IP Address to an ASCII dotted decimal string t
// @param ip the netburner's representation of an IP Address
// @param retAscii a pointer to the string where we will put the IP address
//===========================================================================
void NNbSysUtils::IpToAscii( IPADDR ip, char* retAscii)
{
//cast the longint to byte and use array references to get to each byte
//to easily convert one octet at a time
uint8_t* ipb= reinterpret_cast<uint8_t*>(&ip);
siprintf(retAscii,"%03d.%03d.%03d.%03d",ipb[0],ipb[1],ipb[2],ipb[3]);
}

Just modify the code for ShowIP :
Code: Select all
void ShowIP( IPADDR ia )
{
PBYTE ipb = ( PBYTE ) & ia;
iprintf( "%d.%d.%d.%d", ( int ) ipb[0], ( int ) ipb[1], ( int ) ipb[2], ( int ) ipb[3] );
}
Instead of using printf, load a buffer with siprintf, (or safer) with snprintf then write the buffer.

There are lots of ways to do things....
Another way to do it using the HTML variable functions,
the functions are designed for use on a web page, but can also be used to write human readable stuff to and fd/socket
#include <htmlfiles.h>
WriteHtmlVariable(my_socket_or_fd,IPCAST(ip));
If you want to you can use ANY of the WriteHtmlVariable functions:
void WriteHtmlVariable(int fd, char c);
void WriteHtmlVariable(int fd, int i);
void WriteHtmlVariable(int fd, short i);
void WriteHtmlVariable(int fd, long i);
void WriteHtmlVariable(int fd, BYTE b);
void WriteHtmlVariable(int fd, WORD w);
void WriteHtmlVariable(int fd, unsigned long dw);
void WriteHtmlVariable(int fd, const char *);
void WriteHtmlVariable(int fd, MACADR m);
