I am trying to copy a byte in hex into a char buffer...
char str[15];
memcpy (str,"\x11",1);
However I need calculate the byte I am copying, dynamically, and put it in the char buffer as hex numbers...
so far I have tried using sprintf ...
int int_offset=17; //hex 11
sprintf (str_offset, "%02x", int_offset); // int int_offset=17;
This gives the correct output (hex 11)
now the problem is copying the contents of str_offset AS HEX VALUES into str (the char buffer)
when memcpy is used the values are copies as ASCII values, not hex !.
I have searched the for the answer and tried many things with the debugger , yet been unsuccessful.
Would be very grateful for any pointers ....
Code:#include <stdio.h> #include <string.h> int main () { char str[15], str_offset[4]; int int_offset=17; sprintf (str_offset, "%02x", int_offset); memcpy (str ,str_offset,2); return 0; }
