Reading Data From Buffers!!

Hi Naveen

You can print that buffer in binary or hex or ascii or deciman or any other format.

like:-

int x = 0x12345678;
int buffLen = 4; // you can set it according to your buffer length.
unsigned char *p = (unsigned char *)&x; // you can use here your buffer's address instead of &x
for(int i = 0; i < buffLen; i++)
{
    printf("\n Value at location \t%X is\t%X", p, *p);
    p++;
}

// warning this may cause segmentation fault.

Well, we can read data from a buffer, that's for sure :). What we need is buffer start address and its size. Just assigning buffer start address to void* or char* or byte* (using cast when needed) is enough.
Printing your buffer out is not that straightforward, however. You must make decision on the output format you would like to see. Would you like to interpret your buffer as array of chars in one of encodings (ASCII, Unicodes etc)? Or you don't care about your output having meaning at least sometimes? In the first case you're free to use printf() function or stdout. Otherwise... well, printf() can help you again: to write your buffer out in hex you can use it too, printing byte by byte, in a manner described here[^] (I guess you'd need to use something like

printf("%X", (unsigned char)array_item[i]);

or

printf("%hhX", (char)array_item[i]);

)

You could also try to provide
the serializing from/to a buffer for your data class
and its output as well (such class will know its members' types) :)
