C Programming: Convert Hex Int to Char*

Question

My question is how I would go about converting something like:

    int i = 0x11111111;

to a character pointer? I tried using the itoa() fun

Answer 1

Using the sprintf() function to convert an integer to hexadecimal should accomplish your task.

Here is an example:

int i = 0x11111111;

char szHexPrintBuf[10];

int ret_code = 0;

ret_code = sprintf(szHexPrintBuf, "%x", i);

if(0 > ret_code)
{ 
   something-bad-happend();
}
