inet_addr Equivalent

inet_addr Equivalent

[shesha bhushan]

Hi all,

IF i want to use the inet_addr in kernel modules, then how to use. What is 
the equivalent function to this or which is the header file that I have to 
include. If I include "arpa/inet.h" and compile as kernel module, I gives 
whole bunch of errors.

So please help me how to convert doted IP address to unsigned long inside 
kernel modules. All help is very mucg apperciated.

Tahnking You
Shesha

Hi,

Look at : 
/* Convert from presentation format of an Internet number in buffer
   starting at CP to the binary network format and store result for
   interface type AF in buffer starting at BUF.  */
extern int inet_pton (int __af, __const char *__restrict __cp,
                      void *__restrict __buf) __THROW;

If it doesn't work look in the libc source code :)

regards,
Michael

may be you can write your own function... I had my implementation that 
works, it should for you too...  just take a look at the bottom.

	unsigned int inet_addr(char *str)
	{
	  int a,b,c,d;
	  char arr[4];
	  sscanf(str,"%d.%d.%d.%d",&a,&b,&c,&d);
	  arr[0] = a; arr[1] = b; arr[2] = c; arr[3] = d;
	  return *(unsigned int*)arr;
	}
